On Wednesday, Nov. 3 at 3:15 p.m. in Hill Auditorium of Barrows Hall, Yeongseong Jo will be speaking in the fall 2021 colloquium for the Department of Mathematics and Statistics. His talk will be on “The Riemann zeta function toward the automorphic L-function”: The Riemann zeta function is one of special cases of harmonic series that we are familiar with. The history of the Riemann zeta function goes all the way back to Euler. Strikingly, this series at certain points implies interesting phenomena in number theory such as the prime number theory. However, lots of properties have still not been explained.
