摘要
We characterize spin initial data sets that saturate the BPS bound in asymptotically AdS spacetimes. Our results show that (1) null imaginary Killing spinors give rise to codimension-2 foliations corresponding to Siklos waves, and (2) any imaginary Killing spinor of mixed causal type can be reduced to a strictly timelike or null spinor. This is joint work with Sven Hirsch.

我的研究方向是几何分析和广义相对论,目前主要研究标量曲率和广义相对论中的几何问题。我应用偏微分方程,特别是椭圆方程,来研究几何问题。
