Vacuum initial data with minimal decay and borderline decay
Dawei Shen, Jingbo Wan
In this note, we show that the conical solution-operator method of Mao-Tao in [Localized initial data for Einstein equations] applies to a simple construction of vacuum asymptotica…

Formation of trapped surfaces for the Einstein--Maxwell--charged scalar field system
Dawei Shen, Jingbo Wan
In this paper, we prove a scale-critical trapped surface formation result for the Einstein--Maxwell--charged scalar field (EMCSF) system, without any symmetry assumptions. Specific…
