题目：Causality of Killing vector fields and Killing spinors

摘要：We analyze the causal type of both Killing vector fields and Killing spinors. As an application we give a proof of Bartnik's stationary vacuum conjecture from 1989 and geometrically characterize Siklos wave spacetimes. This talk is based on joint work with Lan-Hsuan Huang and Yiyue Zhang.
