题目:Metrics of Eguchi-Hanson and Horowitz-Myers types with the negative constant scalar curvature

报告人:张晓教授(中科院数学所/广西大学)

Abstract:

ALE metrics were used to constructed counterexamples of Hawking-Pope's generalized positive action conjecture by LeBrun in 1988. In this talk, we construct two types of Eguchi-Hanson metrics with the negative constant scalar curvature. One type metrics are ALH and allow the negative total energy. We also construct metrics of Horowitz-Myers type with the negative constant scalar curvature and verify a new positive energy conjecture of Horowitz-Myers for these metrics. The talk is based on the recent joint works with Junwen Chen and with Zhuobin Liang.
