题目：An Hermite-Minkowski theorem for perverse sheaves

报告人: 胡昊宇 （南京大学）    

摘要：In 2012, Kerz and Esnault proved Deligne’s finiteness theorem for l-adic sheaves, which says that the number of geometrically irreducible l-adic local systems on a smooth variety of positive characteristic is finite, with bound ramification along a normal compactification and ranks. In this talk, I will present a generalization and a new proof of this theorem. The new ingredient is a universal bound of Betti numbers for étale sheaves with wild ramifications. This is a joint work with Jean-Baptiste Teyssier.
