摘要：The calculation of Betti numbers of étale sheaves is an important theme in étale cohomology theory and has many applications in number theory. In this talk, I will explain a boundedness result for the Betti numbers of étale sheaves with bounded ramifications along the boundary on affine smooth varieties of positive characteristic. This is a joint work with Jean-Baptiste Teyssier.
