几何与拓扑讨论班：Lars Andersson Gravitational instantons and special geometry
Date: Monday, March 31
Venue: 海纳苑2幢204室
Speaker: Lars Andersson (BIMSA)
Pretalk: General Relativity and Geometry
Time: 16:15-16:45
Abstract: I will give a brief introduction to the Einstein equation of general relativity and mention some open problems related to it.
Research talk: Gravitational instantons and special geometry
Time: 16:45-17:35
Abstract: Gravitational instantons are Ricci flat complete Riemannian 4-manifolds with at least quadratic curvature decay. Classical examples include the Taub-NUT and the Euclidean Kerr instanton. In this talk I will present some recent results on classification, stability, and conservation laws, for instantons with special geometry.
