摘要
Given any initial data set satisfying the charged dominant energy condition and saturating the mass–charge inequality, we show that it embeds into a Majumdar–Papapetrou spacetime. The proof uses the degree of the Tod map to turn the possible null degeneration of the associated spinorial current into a topological obstruction. The main idea of the proof was suggested by GPT.

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。
