## SIMIS Seminar on Geometric Analysis and PDEs: Hamilton’s pinching condition and conformal deformation

Speaker: 来米加教授（上海交通大学） Abstract: Hamilton’s pinching conjecture asserts that if a three dimensional manifold satisfies a Ricci pinching condition (, for some small ), then M must be compact unless it is flat. This conjecture was recently proved by Lee and Topping. In this talk, I will first talk about the origin of this conjecture, which is a …
