The 15th Annual Pi Mu Epsilon Lecture will be given by Professor Ken Ono, Thomas Jefferson Professor of Mathematics and Chair in the Department of Mathematics at the University of Virginia.

The PME lecture will take place on **Wednesday, April 13, 4-5 pm, via Zoom (ID: 947 8772 9456; Password: MATH-CLUB) and broadcasted in 115 Avery Hall**.

## What is the Riemann hypothesis, and why does it matter?

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 one-half. 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.

### About the Speaker

Ken Ono currently holds the title of Thomas Jefferson Professor of Mathematics at the University of Virginia and is Chair of the Mathematics Section in the American Association for the Advancement of Science. He was formerly (2018-2021) a Vice President of the American Mathematical Society. Previously, Ono held positions at University of Wisconsin–Madison and Emory University. He completed his BA at the University of Chicago in 1989 and his Ph.D. at the University of California, Los Angeles, in 1993. Ken Ono is a world expert in number theory with more than 200 papers. He is famous for solving Ramanujan's partition congruences and proving the umbral moonshine conjecture. He also has extensive experience working with undergraduates in various REU programs. Besides mathematics, Ken Ono enjoys surfing, SCUBA diving, cycling, running, and swimming. He has competed in World Triathlon Cross Championships events while representing the United States. He is also University of Virginia Swimming's "secret weapon."
