The Angular Momentum Penrose Inequality
Da Xu
We prove the Penrose inequality with angular momentum for asymptotically flat, axisymmetric vacuum initial data sets containing a stable marginally outer trapped surface. This ineq…

The Spacetime Penrose Inequality: Conditional Results for Stable MOTS and General Trapped Surfaces
Da Xu
We present a rigorous proof of the Spacetime Penrose Inequality relating the ADM mass to the area of trapped surfaces in asymptotically flat initial data sets satisfying the domina…
