Speaker:赵永强（浙江西湖高等研究院） Venue: B1044 Time: 2017年10月12日 9:00-10:00 Title:Counting integral points w.r.t. codimension two subvarieties. Abstract:In this talk, we will propose a very general new counting question in analytic number theory, which unifies many counting questions with coprime conditions into a single framework. We will give some general results on affine spaces and projective spaces, and discuss their applications. This is a joint work with David McKinnon.
