Title：Hypergeometric systems on reductive groups
Abstract:
Hypergeometric differential systems on reductive groups are introduced by Kapranov. We study the arithmetic counterpart, that is, the l-adic hypergeometric geometric sheaves and the p-adic hypergeometric arithmetic D-modules on reductive groups, and discuss their application to the study of exponential sums on reductive groups.
