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.
