题目： Ramification bound of nearby cycles of l-adic sheaves

报告人：胡昊宇 （南京大学）

Abstract : In this talk, we use Abbes-Satio’s ramification theory and the theory of singular supports and characteristic cycles to studying the bound of ramification slopes of the nearby cycle of an l-adic sheaf on a smooth fibration ramified along a special fiber over a base of dimension 1. As an application, we obtain various properties for the wild ramification of l-adic sheaves on abelian schemes over curves.
