Introduction to the new Data Science Major
Presentation by Doug Pellatz, Senior Academic Advisor
Staring with the upcoming Fall 2023 semester, the University will launch a new major program in Data Science. The Data Science major is a collaboration between the Department of Mathematics, the Department of Statistics, and the School of Computing, and degrees with the Data Science major will be offered by the three Colleges where these areas reside. This presentation will provide information about the new Data Science major including its core course requirements and eight focus area options. Since this major will be offered in three Colleges, the differences between the three degrees will be highlighted. The overlap with the current Mathematics major will also be discussed.

16th annual Pi Mu Epsilon Lecture by Professor Alex Iosevich of University of Rochester
Title: The beautiful world of Erdős geometry: points, lines and distances
Abstract: Paul Erdős considered his greatest contribution to geometry to be his distance problem, which asks, how many distinct distances are determined by N points in ddimensional Euclidean space, d≥2. Generically, the number of distances is approximately N^{2}, but distance may repeat, so the critical question is, what is the smallest possible number of distinct distances? We are going to discuss some elementary aspects of this problem, related problems in combinatorial geometry, and some unexpected applications. The emphasis will be interconnectivity between the various areas of modern mathematics.

Title: Three PredatorPrey Models and Their Analysis
Abstract: Predatorprey models are among the most fundamental models in mathematical biology. They typically include processes for prey growth, predator death, and predation, but these processes can be modeled using different functions. In this talk, we begin with the most basic predatorprey model and continue with two more sophisticated models. Along the way, we'll look at graphical and analytical methods for finding the longterm behavior of dynamical systems with two components.

Title: OneCut Origami
Abstract: The noble pursuit of origami has been around for centuries. Throughout that time, there has been one question that’s been burning inside of everyone’s head: Given a straightedge polygon, can you fold the shape such that all of its lines lie on top of each other? It took a few hundred years to sort out the details, but we’ll go over it by the end of this talk. That is, not before we go over the history of the problem and the many people who have contributed to it. Audience participation is encouraged and appreciated!

Math talk by Lawrence SeminarioRomero
Title: Modeling plantherbivore interactions when a type III functional response is present
Abstract: The functional response measures the consumption rate per predator as a function of prey density. The most notable functional response models are those attributed to C.S. Holling who described three types: I, II, and III. The type II and III Holling functional responses are empirically supported, with type I being the least realistic for predators. A lot of previous work on modeling predatorprey interactions utilized a type II functional response. For this talk, we will analyze a system of nonlinear ordinary differential equations that models plantherbivore interactions when a type III functional response is involved. The analysis consists of nondimensionalization, and the existence, uniqueness and stability of equilibria. We also use numerical estimates obtained from MATLAB to determine

Title: REUs, what, why, and how.
Abstract: What are REU's and why should you apply? REU stands for Research Experience for Undergraduates and is held in many fields. It started in mathematics around 198283 when NSF started funding a limited number of universities for summer research programs. The program stopped for a couple of years due to budget cuts and restarted in 1987 and has been running since. The idea remains the same: exposing undergraduate students to research in mathematics. Whether you are considering graduate school or industry, an REU is an invaluable experience. In this talk, I will provide information about REU's, the application process, and what to consider (or not consider!) when applying.
Pizzas and sodas will be provided!

Title: Exploring the Navier Stokes Equations and their consequences
Abstract: As an undergraduate, I wondered how people went from being a calculus student to doing research in mathematics. I've learned that sometimes, all it takes is a problem to inspire you. In this talk, we will explore the (problematic) set of equations that inspired methe Navier Stokes Equations. Additionally, I will discuss some of my current interests and projects involving nonlocal (peridynamic) operators and computations in Matlab.

Title: Chaos is a friend of mine: Dynamical systems theory enables design of deep space missions and fluid robots
Abstract: The geometrical framework of dynamical systems theory was originally developed by Poincare to study the complicated (chaotic) dynamics of the three bodies moving under mutual gravitational forces. In this talk, we will first discuss the application of this theory to explain the (sometimes puzzling) motion of celestial bodies, as well as to design nonintuitive fuelefficient space missions to moon and beyond. A typical particle meanders through the phase space of an Nbody problem by travelling on invariant manifolds that connect different equilibria and periodic orbits. These invariant manifolds, created by the competing gravitational forces, act as `interplanetary superhighways'. Next, we will discuss the far reaching generalizations of this framework in the context of fluid mechanics, where we extend this theory to infinite dimensions and explain the complex dynamics of a new class of robotic fluid systems known as `active nematics’.

Pi Mu Epsilon Lecture by Professor Ken Ono (Thomas Jefferson Professor and chair of Math Department, University of Virginia)
Title: What is the Riemann hypothesis, and why does it matter?
Abstract: The Riemann hypothesis provides insights into the distribution of prime numbers, stating that the nontrivial zeros of the Riemann zeta function have a “real part” of onehalf. A proof of the hypothesis would be world news and fetch a $1 million Millennium Prize. In this lecture, the speaker will discuss the mathematical meaning of the Riemann hypothesis and why it matters. Along the way, he will tell tales of mysteries about prime numbers and highlight some recent advances.

Title: “Surprising connections between tornadoes and … fracture?!? and How peridynamic (nonlocal) models can help improve safety”
Abstract: Materials can fail from static or dynamic (impact) loading. The collapse of the Champlain Towers South, a 12story beachfront condominium in the Miami suburb of Surfside, Florida, in 2021 happened from corrosioninduced fracture under static loading. Windows of spacecraft or in buildings in the tornado alley, can fail because of impact with debris. If we could simulate these types of phenomena and predict what would happen under various loading scenarios, we could improve the design of materials and structures to increase the safety and avoid catastrophic failures. The problems mentioned above tend to be difficult to predict using computational modeling and simulation: fracture in glass appears, at first, to be unpredictable, with various types of cracks intermingled; corrosion attack on the reinforcing bars in concrete leads to expansion of the bar (from lowerdensity corrosion products) which induces tensile loads and cracks growing in concrete in unexpected places. For the past 5060 years, the approach for predicting this behavior was via mathematical models based on Partial Differential Equations (PDEs) and computational models (e.g. the Finite Element Method) that approximate solutions of such PDEbased problems. These descriptions, however, have severe limitations and lead to solutions with mathematical singularities that do not exist in reality. These models also require adhoc rules for how damage should form in a material and how it should evolve (turn left, right, go straight, spread diffusely?), which rarely match the experimental observations. In this talk, I will explain how our novel peridynamic (nonlocal) mathematical models have been able to predict, for the first time ever, physical behavior which, up to that point, was considered “unpredictable”. I will also discuss some recent computational methods that allow us to speedup the computation of these nonlocal models.

Title: Flexagons: Mathematics and Paper Folding
Abstract: In 1939 Arthur Stone folded a strip of paper into a flat hexagon with nice symmetry. He discovered that he could pinch his hexagonal creation and turn to three different faces. He and his classmates formed a flexagon committee to study different folded paper objects that can "flex" between a set of states. In this talk, we will explore what kind of flexagons and state graphs are possible and how to make your own flexagons. We will have lots of readymade flexagons to play with and paper for you to make your own. We will also discuss the known results about these playful objects.

Pi Mu Epsilon Lecture by Professor Ben Brubaker, Head of School of Mathematics, University of Minnesota
Title: Setting your undergraduate research on fire: A parable through ice.
Abstract: We'll talk about recent research in representation theory and combinatorics done by and in collaboration with undergraduates in various formats (including REUs and other summer programs). On the research side, it is a chance to explain how special functions in representation theory arise as generating functions on "icetype" lattice models and how methods from statistical mechanics allow us to draw conclusions about them. We'll also use each example as an opportunity to talk about the various research formats and programs for undergraduates, and what the benefits, goals, and future possibilities of such formats might be as we are all acquiring new skills and new modes of delivery. For the mathematics, no prior familiarity with combinatorial representation theory is required and terms and concepts will be introduced from scratch.

Math talk by Dr. Beemer, University of WisconsinEau Claire
Title: Coding theory: shielding data from corruption
Abstract: Whenever data is transmitted or stored, the information is vulnerable to errors that can be either random or adversarial in nature. The field of mathematical coding theory addresses this by introducing redundancy into information, resulting in encoded data. In this talk, we will introduce some fundamental concepts in coding theory, including measures of reliability and efficiency, as well as an important class of codes called linear codes. Linear codes are widely used in practice, and their symmetry allows us to more easily understand and compute measures of their performance. However, we will see that this same symmetry makes linear codes a poor choice when a powerful adversary can tamper with transmissions. We will discuss the advantages of introducing a small amount of nonlinearity in this setting, resulting in codes that can both correct random errors and detect adversarial tampering.

Title: From Dice to Polynomials, and Back to Dice
Abstract: Popular board games like Monopoly, Settlers of Catan, and Backgammon rely on a common mechanic—rolling two 6sided dice and adding the resulting values. But is the labeling on these dice unique? That is, can we change the numbers on the dice so that the probability of getting 2 through 12 remain unchanged? If so, how many labelings are there? In this talk, we'll discuss how polynomials (and more broadly, power series tricks from Calculus) can help us find the answer!

Title: The NavierStokes Equation for Fluid Dynamics and Its Application in the Movie Industry
Abstract: My Professor Otaku lecture series employs visual pop cultures to explain STEM in informal and casual ways. This Professor Otaku lecture for UNL Math Club is about fluid dynamics, a branch of physics to study motions of fluids, and mathematics, a crucial part of fluid dynamics. In this talk, I will introduce the NavierStokes equation for incompressible flow of Newtonian fluids, which is one of the Millennium Problems, and explain how analytic solutions of the simplified NS equation are related to real flows. Then, I will introduce how solving the NS equation computationally is used in the movie industry.

Math talk by Jack Jeffries
Title: Sharing a square pizza
Abstract: We might not have had this problem recently, but here's a problem from more normal times. Pizza, as we all know, should be eaten in triangular slices. Given a square pizza, is there a way to cut it into triangular slices of equal size? If we want two, four, or six slices, you'll succeed. If we want three, five, or seven slices, we'll at least struggle. In fact, it's impossible to cut a square into an odd number of triangles of equal area. Even more fun than this fact is the surprising set of tools we'll use to see it. Only a basic familiarity with pizza is assumed as background.

Title: Symmetry and [Inverse Semi]Groups
Abstract: A group is an important mathematical object that captures the idea of symmetry. For example, rotations and reflections of an equilateral triangle can be expressed as a group. But what about the symmetries of something like the Sierpinski Triangle, which is made up of three smaller Sierpinski Triangles? In this talk, I will define what a group is and give some examples of groups. Then we will look at how we can tweak the definition in order to capture these "partial symmetries".

Talk by Michael Bieterman from the Boeing Company
The Life and Times of a Mathematical Kid  UNL Math Major and Beyond
Michael Bieterman grew up in Omaha, NE and was an undergraduate math major at UNL, receiving his B.A. degree in 1975. He earned his M.S. and Ph.D. in mathematics from the University of Maryland at College Park. During most of graduate school and for several years after, Michael held applied math research positions at the National Institutes of Health in Bethesda, Maryland. He also did a bit of consulting and teaching following his doctorate and spent a very brief time as a visiting scientist at Yale University. For thirtysix years, Michael has had five or six careers within Boeing’s Applied Math group in the Seattle area, where he continues to work as a Technical Fellow.
Michael will tell a story describing his career trajectory, including time at UNL, a simple model for career decision making, and factors governing his choices along the way. His presentation will include descriptions of some math applications, his applied math passions, and what it feels like to do industrial math.

This Title is False: Hilbert, Gödel, Turing and the Beautiful Futility of Mathematics
Presentation by graduate student J.D. Nir.
In a well known <a, href="https://xkcd.com/435/"> XKCD comic, scientific fields are arranged by purity with mathematics all the way at the end labeled "more pure." We love math because it is rigorous and clear cut; there's a right answer and we know how to find it. We deal with truth and certainty, right?
In this talk, we examine the foundation of these claims. Does math rest on a solid bedrock of truth, or is it turtles all the way down? What does it mean to be "true" anyway? We will investigate the very heart of mathematics and find it is not the welloiled machine we pretend it is. After pulling back the curtain and seeing math for what it really is, will you still find it beautiful?

Using Math to Save Lives
Presentation by Lucas Sabalka, senior research officer at Ocuvera.
I think of mathematicians as problem solvers. I’ve been lucky enough in my career to be able to think about plenty of interesting problems. I’ll talk about a few of them, including predicting algal blooms in lakes, modeling the efficiency of nextgeneration solar cells, and creating 3D scans of people for formfitted braces. My current job is with a company called Ocuvera, where the math I do is used to prevent people from falling in the hospital, literally saving lives. My job is to create and train the algorithms we use to find and monitor each patient and teach the computer what behavior increases a patient’s risk of falling. If the algorithms think that a patient is doing something dangerous, our system sends a live streaming video to nurses so they can see what’s happening and respond appropriately: see that the alert is a false alarm, communicate to the patient that they’re on their way, or get to the patient as fast as possible.
 Thursday, March 14, 56 pm in 351 Avery Hall: Countering Gerrymandering with Math

Presentation by professor Steven Dunbar

Gerrymandering is the ageold practice of manipulating voting districts for partisan gain. Recently there has been a surge of interest in using mathematics to detect and study gerrymandering. In fact, this topic is currently a combination of law, political science, politics and mathematics.
This talk will focus on a particular aspect of the mathematics behind the study of gerrymandering, namely the efficiency gap. This is an algebraic formula which appeared in arguments before the Supreme Court last October. Prerequisites for this talk are at the level of calculus and elementary algebra.

 Thursday, September 13, 56 pm in 351 Avery Hall: Building spheres using puzzle pieces

Presentation by professor Alex Zupan.
Topologists like to break up complicated objects into small, manageable pieces. As a simple example, a natural way to split the surface of the earth is to divide it into two pieces, the Northern and Southern Hemispheres. Of course, the earth's surface can also be cut into many more components, and a natural question is to determine how each of these decompositions is related to any other. We consider the problem of cutting up a sphere into topological puzzle pieces in dimension two, three, and four, describing some recent progress (joint with Jeffrey Meier) on a big, unsolved problem in this area.
 Friday, October 19 45 pm in 115 Avery Hall: 12th annual Pi Mu Epsilon Lecture

A New Look at an Old Calculus
Presented by professor Robert Ghrist  Andrea Mitchell professor at the University of Pennsylvania.
Calculus has been around for centuries and has a long tradition of applications spanning the modern history of science. However, the current age is characterized by a sweeping array of new potential applications—to machine learning, AI, robotics, neuroscience, genetics, and much more. In addition, both our curricula and our default modes of instruction (chalk, paper, 4color texts) are not keeping pace with innovation. This talk will be an argument for updating both the content and the mode of visualization of calculus. There will be lots of pictures, new applications, and even a little bit of the mathematics that lies beyond calculus.

 Thursday, January 25, 56 pm in 351 Avery Hall: Graphs on a Train !
 Presentation by professor Ranjan Rohatgi from St. Mary's College, IN
In this talk we will characterize and count graphs that have two properties: each vertex is incident to three edges and the graph must arise from a permutation. It turns out that essentially every graph of this type can is made up of subgraphs we call boxcars, which, when combined appropriately, means that all of these graphs look like trains! This is joint work with Aysel Erey, Zachary Gershkoff, and Amanda Lohss.

Thursday, October 19 56 pm in 351 Avery Hall: 1distance and almost1distance sets in R^{n} Presentation by professor David Galvin (Notre Dame U.)
A 1distance set is a set of points any two of which are the same distance apart (so the vertices of an equilateral triangle form a 1distance set in the plane, and the vertices of the regular tetrahedron form one in space). It's well known that the largest 1distance set in ndimensional space has size n+1. While this is a geometric fact, it admits a lovely linear algebra proof.
In 1962 Danzer and Grünbaum asked how large a set can be if it is almost 1distance  pairs of points are close to the same distance apart. They made the reasonable conjecture that the largest almost1distance set is never much larger than the largest 1distance set. Twenty years later, Erdős and Füredi spectacularly disproved this using a probability argument.
Erdős and Füredi's work was highly nonconstructive. Nicely illustrating that one can never predict where a mathematical problem is going to go next, recently Zakharov, a highschool student in Moscow, revisited the linear algebra approach, and improved on Erdős and Füredi's result  this time in a completely constructive way.
I'll talk about some of this work, and mention a few nice open questions.

Finding a combinatorial characterization for rigid barandjoint frameworks in dimensions higher than 3 is an easytostate yet elusive, long standing open problem in rigidity theory, originating in two geometry papers from the 19th century of the renowned physicist James Clerk Maxwell. I will summarize our current state of knowledge on Maxwell's problem, and present recent developments leading to a surprising range of applications, from folding robot arms and origami to anayzing the flexibility of molecules and designing materials with unusual mechanical properties.
No advanced prerequisites are necessary. To help build the geometric and kinematic intuitions, the relevant mathematical concepts and techniques will be introduced primarily through physical models and animated graphics.

 Errors, Eavesdroppers, and Enormous Matrices
Abstract. Join us for a tour of the mathematics of information security! Cryptography aims to protect information from malicious eavesdroppers. Coding theory aims to protect information from inadvertent errors  consequences of a noisy environment. These are two very different problems  but amazingly enough, solutions to one problem can be used to build solutions to the other. We'll talk through some fundamental principles and key ideas in both coding theory and cryptography, with an end goal of appreciating their intersection: the future of postquantum security.

Thursday, Sep 3, 5:006:00 pm in Avery 110: Talk by Professor Adam LariosCan mathematicians compute our way out of doing math?
As computers gain a stronger hold in mathematics, should mathematicians start to worry? Computers obviously depend on mathematics, but more and more areas of mathematics are starting to depend on computers. Does this mixture violate the purity of mathematics? Will the beauty of mathematics be forgotten, reduced to cold hard computation? Fortunately, the situation may be not so scary. We will see many examples of mathematics and computers living happily together. Moreover, pairing these disciplines can be beneficial to both sides. I will argue that computers do not spell doom for mathematics; indeed, they make mathematics more exciting than ever.
And, of course, PIZZA!

Abstract. There are many ways of comparing polygons. For instance, we could compare their areas or perimeters. We could also ask if they are similar or congruent. In this talk we will explore a notion of comparing polygons, called equidecomposability, that involves breaking them into pieces and comparing the pieces. We'll look at some examples and then sketch a proof showing that equidecomposability is equivalent to having the same area.

Thursday, March 13, 5:006:00pm in Avery 106: Talk by Professor AbdulAziz Yakubu:
Mathematical Ecology: Modeling Fish Harvesting Strategies
Abstract. Overfishing, pollution and other environmental factors have greatly reduced commercially valuable stocks of fish. In a 2006 Science article, a group of ecologists and economists warned that the world may run out of seafood from natural stocks if overfishing continues at current rates. We will use simple models to explore the interaction between constant proportion and periodic proportion harvest policies. We will analyze how they might be applied to the Gulf of Alaska Pacific halibut fishery and the Georges Bank Atlantic cod fishery, based on harvesting data from 1975 to 2007.
This event is sponsored by the Nebraska Math Scholars program, funded by the National Science foundation.

Thursday, March 20, 5:006:00pm in Avery 12 (Hitech classroom). Professor Eric Eager from University of Wisconsin  La Crosse will present:Computational Experiments in Biology: Modeling, Analysis and Simulation of Disturbance Specialist Plants
We will use probability theory and computer simulations to explore how populations respond to uncertain environmental conditions. We'll consider a "disturbance specialist" plant, which is a plant that will die off unless a disturbance, such as a burrowing animal, shakes loose the seeds in its seed bank. We will illustrate this with a wild sunflower, a disturbance specialist plant that is native to Nebraska and Kansas.
This talk will be held in the hightech classroom Avery 12, so you can run simulations in R.
If you prefer to use your own computer, feel free to bring it. We'll help you install the program and run the code.
You can optionally predownload R for free here.

Thursday, February 14 at 4:30pm in Avery 108: Talk by Professor Keri Kornelson:
Loosen up! An Introduction to Frames.
Abstract. An orthonormal basis (ONB) in a finitedimensional space like R^{n} has a lot of useful and efficient properties, which is why a great deal of what you learn in linear algebra makes use of ONBs. There are a wide range of applications to other areas of math and science as well where ONBs play a crucial role. But in this talk, we will discuss some of the drawbacks of ONBs. We find that a somehow looser set of vectors (called a frame) might maintain the positive attributes of the ONB while overcoming some of the flaws.

Counting techniques and the game SET
Abstract. SET is a multiperson card game in which the goal is to collect particular sets of three cards from a group of 12 (or more). The person with the most SETs by the end of the game wins. We will use different counting techniques to answer some interesting questions about the game, including: what is the size of the largest group of cards that does not contain a SET?, and, what is the most common type of SET? It turns out, one of the questions above was actually answered 11 years before the game was invented! In this talk we will relate this proof back to the game SET and discuss some generalizations.

Penrose Tilings: "Impossible" Symmetries in Math, Crystals, and Art
Tiling a floor with a few standard tiles has been a practical problem for a long time. It is also a mathematical problem and, in spite of its long history, there have been surprising recent discoveries. There are two tiles, discovered in the 1970's, that tile the whole plane, but only in a nonrepetitive way, something that had been thought to be impossible. We'll talk about what a nonrepetitive tiling is, what we know about them, and a bit about how they appear in both physics (as quasicrystals) and art (as Islamic building decorations of the 13th Century).
And of course there'll be Pizza!

 Thursday, January 12, at 5:00 pm Avery 347: Talk by Dr. Marta Lewicka (U. Pittsburg)
 Title: How to understand shapes of leaves and flowers through Mathematical Analysis and Geometry
Abstract. In certain circumstances, growing tissues such as leaves, flowers or some small marine invertebrate organism develop curious wavylike patterns, resembling curves and ruffles at the edge of a thorn plastic sheet. It turns out that 'morphogenesis by growth' can be rigorously studied through a mathematical model, in which the distances between points (e.g. cells) are measured in a nonstandard way. In this elementary talk, I will try to explain what Mathematical Analysis, Algebra and Geometry have to do with this business.
Preceded by a Brown Bag Lunch with the speaker in Avery 348, 12:30  2 pm.
Everyone is welcome! Come to socialize and enjoy the refreshments and sandwiches (firstcome, firstserved)!

Thursday, February 2, at 5 pm in Avery 108: Talk by Charles Larrieu (UNL senior math major) Title: A Friendly Discussion of Light, Space, the Universe, and Everything...And Groups!
Abstract. This talk is mostly meant to be a justification for the statement, "REU's and other Undergraduate Research Experiences are awesome." To this effect, I will speak very generally about some of the mathematical ideas that I studied in the REU on Geometry through Lie Groups last summer at the University of Utah. These ideas include group actions, smashing shapes with textbooks, Cayley Graphs, living in nonEuclidean universes, and light in Einstein's universe.

Thursday, April 5 at 5 pm in Avery 106: Talk by graduate student Derrick Stolee Title: Symmetry, Groups, and Graphs
Abstract. Symmetry is something that everyone understands intuitively, since we see it so frequently in art, nature, and ourselves. We will explore a mathematical version of symmetry called group actions. In particular, we will investigate symmetries of combinatorial objects called graphs. Graphs have many practical purposes, but mostly we find that every type of symmetry imaginable can be encoded into a graph.
Thursday, April 12 at 5 pm in Avery 106: Talk by senior math undergraduate Adam AzzamTitle: Sperner's Lemma and its Continuous Corollaries
Abstract. In this talk I will present a celebrated mathematical result known as Sperner's Lemma. While it originated in the context of combinatorics and graph colorings, it also has surprisingly powerful applications to analysis and topology. In particular, I'll use Sperner's Lemma to prove the Intermediate Value Theorem, the Brouwer and Kakutani Fixed Point Theorems (with applications to nonlinear equations), and establish the existence of Nash Equilibria for nperson games with mixed strategies.

Reflections on a planar landscape.
Abstract. We will make a foray into a beautiful interplay between geometry and computer science. For reflections a, b, and c about three lines the plane, a composition of these three functions (for example abaccbcbabcaba) may end up not moving any of the points in the plane. We'll talk about deciding when this happens, and what sort of computer  if any  can determine the answer.

 Join us for some pizza, refreshments, and listen to Adam Azzam speak about his exciting research work at an REU site this summer:
Embroidering in Hilbert Space.
Abstract. If you ask a firstyear calculus student how class is going, they might beg you to "make the derivatives stop!" Underlying this futile request lies a subtle question: how many functions can you "get" by taking the derivative of a given function? Start with a polynomial? The derivative eventually smashes it to zero. Start with sine or cosine? It eventually repeats. Start with an exponential? You can't expect much change. How chaotic can this predictable process of taking derivatives be? Wild. In this talk, I'll present some basic theorems and some new results demonstrating how chaotic these linear functions can be.
 Friday October 14: AMS Conference Poster Session

My path from Math 221 to Neuroscience
Abstract. Since graduating from the UNL math department as an undergrad in 2001, I have been forging a career at the interface of dynamical systems mathematics and cuttingedge experimental neuroscience.
I did my graduate work at Boston University, using differential equations to study brain rhythms in schizophrenia. Since then, I've been doing research in both experimental and computational neuroscience at MIT and Brown University.
In this talk and discussion I'll take you on a whirlwind tour of the biological topics I've researched, via the gateway of my mathematics education, and talk about the career steps that got me from differential equations class my sophomore year to my current work in electrophysiology and computational neuroscience. I'll be looking forward to your questions about mathematics, neuroscience, and how I've balanced family and career.

Thursday, April 7 at 5:00pm in 106 AveryUNL Math Professor Daniel Toundykov will speak on "Efficient multiplication with the Fast Fourier Transform":
Abstract: Fast arithmetic for large numbers, hundreds or thousands of digits in length, has become increasingly important in number theory research, combinatorics problems, cryptography, and arbitraryprecision computing. However, even specialized computer processors are limited to about 19 significant digits per operation, and must be supplemented by software algorithms to handle higherprecision arithmetic. The standard long division and multiplication procedures are too inefficient for this purpose. I will describe the ideas behind the fastest known multiplication algorithms based on the discrete Fourier transform, and discuss connections of integer multiplication with algebra and complex analysis.

Abstract. A graph is a prime distance graph if its vertices can be labeled with distinct integers such that for any two adjacent vertices, the difference of their labels is prime. Surprisingly, some wellknown theorems and longstanding conjectures in number theory are closely connected to questions about prime distance graphs. In this talk we'll investigate some of these connections and fail to prove any of the longstanding conjectures. No previous knowledge of graph theory or number theory will be assumed.

Baseball Cards and Matrices
Suppose a collector wants to collect a complete set of n unique baseball cards, and he can collect p unique cards in a pack at one time, with replacement. What is the probability he will have his complete set after buying t packs? This ``Baseball Card Collector's Problem", also known as the ``Coupon Collector's Problem", has been thoroughly studied for p=1. However, say the collector wants to have c complete sets instead of just 1. To answer the above question in this case, basic inclusion/exclusion combinatorics will not suffice. Instead, transition matrices representing the probability of going between certain states in the problem give us the tools to formulate probabilities for c=2 and p=1. Tools for higher c and p are demonstrated, but the solutions become very complex. This research was carried out at the Clemson University summer REU, which will be highlighted in the talk.
