Pure Maths Colloquium: Theta series and values of L-functions

Presented by Tobias Berger, University of Sheffield

27 January 2014 16:00 in CM221

Since Euler we know that the value of the Riemann zeta function at
non-positive integers is a rational number. Do these values have any
meaning? The Bloch-Kato conjectures answer this question more generally
for values of so-called L-functions. I will give an introduction to the
conjectures and explain a strategy using theta series first employed by
Hida that continues to yield new results towards them.
