The 13th Annual Pi Mu Epsilon Lecture will be given by Professor Joseph Gallian, the Morse Alumni Distinguished University Professor of Teaching in the Department of Mathematics and Statistics at the University of Minnesota Duluth.

The PME lecture will take place on **Friday, October 11, 4-5 pm in 115 Avery Hall**.

Preceded by reception (refreshments): 3:30 - 4:00 pm, Avery 348.

## Using Mathematics to Create Symmetry Patterns

We explain how to create symmetry patterns using Hamiltonian paths, spanning trees, exponential functions, logarithms, and modular arithmetic. These methods were used to create the image for the 2003 Mathematics Awareness Month poster.

### About the Speaker

Joseph Gallian has been a professor at the University of Minnesota Duluth since 1972. Gallian has authored or edited six books (Contemporary Abstract Algebra, Cengage; For All Practical Purposes, W.H. Freeman (co-author); Principles and Practices of Mathematics, Springer-Verlag; Proceedings of the Conference on Summer Undergraduate Mathematics Research Programs, editor, American Mathematical Society; Proceedings of the Conference on Promoting Undergraduate Research in Mathematics, editor, American Mathematical Society; Mathematics and Sports, Mathematical Association of America) and over 100 articles. Between 1977 and 2019, Gallian ran 40 Research Experience for Undergraduates (REU) programs at Duluth. It is one of the oldest and longest running REUs in the country. Gallian served a 2-year term as the President of the Mathematical Association of America starting in January 2007. In addition, he was co-director of Project NExT from 1998 to 2012, Associate Editor of MAA OnLine since 1997, a member of the advisory board of Math Horizons from 1993 to 2013, and a member of the editorial board of the American Mathematical Monthly for 15 years. Gallian has won both the Allendoerfer and Evans awards for exposition from the Mathematical Association of America (MAA) and was the Pólya lecturer for the MAA from 1999 to 2001. His excellence in teaching earned him the Haimo Award for distinguished teaching from the MAA in 1993 and he was the Carnegie Foundation for the Advancement of Teaching Minnesota Professor of the Year in 2003. In 2019 he received the MAA's Mary P. Dolciani Award for making a distinguished contribution to the mathematical education of K-16 students in the United States or Canada, and in 2011 he received the MAA's Yueh-Gin Gung and Dr. Charles Y. Hu Distinguished Service to Mathematics Award.

The Pi Mu Epsilon lecture series is made possible through the support of the UNL Mathematics Department and the Nebraska Alpha Chapter of Pi Mu Epsilon.
