Title:Boundedness of Betti numbers for étale sheaves
Abstract:The calculation of Betti numbers of étale sheaves has many applications in number theory. In this talk, we discuss a boundedness result for Betti numbers of étale sheaves on smooth schemes with wild ramifications along the boundary. The ramification bound of nearby cycle complexes is involved in the project. This is a joint work with Jean-Baptiste Teyssier.
