Differential Geometry seminar

Speaker: Gao Chen (USTC)Title: Torelli-type theorems for gravitational instantonsAbstract: A gravitational instanton is a non-compact complete hyperkähler 4-manifold with bounded L^2 curvature. In this talk, We will discuss Torelli-type theorems for gravitational instantons. This is a joint work with Jeff Viaclovsky and Ruobing Zhang.
