Inviter:  
Title:
Classification of gravitational instantons
Time & Venue:
2017.6.2 10:00-11:00 N913
Abstract:
In this talk, a gravitational instanton means a non-compact complete hyperk?hler 4-manifold with faster than quadratic curvature decay. I will show that the examples constructed in the first lecture are the only examples. As corollary, I will discuss about the Torelli-type theorems. This is a joint work with Xiuxiong Chen.
