讲座主题：Deligne's conjecture for Rankin-Selberg L-functions

讲座摘要: In this talk, we shall first introduce Deligne's conjecture for critical L-values, which generalizes the famous result by Euler that for a positive integer m, \zeta(2m) is a rational multiple of (2\pi i)^{2m}. We will then refine Deligne's conjecture for Rankin-Selberg L-functions over CM fields. Finally, we will introduce a new strategy to prove this conjecture. This is a joint work with Harald Grobner, Michael Harris, and A. Raghuram.
