Mathematical Science Seminar: Introduction to surgery theory of manifolds

Events

Speaker

Professor Su Yang (Chinese Academy of Sciences)

Abstract

The surgery theory is a main tool to study the difference between homotopy equivalence and diffeomorphism/homeomorphisms of high-dimensional manifolds. In this talk, we will introduce briefly the theory for simply connected manifolds and present some applications, including classification of homotopy spheres, simply connected 4-manifolds.
