题目: An automorphic version of Deligne’s conjecture

摘要: Deligne’s conjecture relates critical values of motivic L-functions and Deligne's period defined as a determinant with respect to certain rational structures. In this talk, we will present an analogue of this conjecture for tensor product of automorphic representations.

题目: Cyclicity of central simple algebras over fraction fields of two-dimensional local rings

摘要: Let K be the fraction field of a two-dimensional complete local domain with finite residue field F, and \ell a prime number different from char(F). Let A be a central simple K-algebra whose Brauer class [A] is of order \ell. We show that the cyclicity of [A] can be tested over local completions of K.
