MONT 214We introduce a new quasilocal mass with interesting properties along null flows off of a 2sphere in spacetime or, equivalently, foliations of a null cone. We also show how certain convexity assumptions along a foliation of a null cone give rise to the Penrose inequality. For monotonicity from a MOTS, one requires these convexity assumptions be sharp, so we explore existence within a Weakly Isolated Horizon. Building on a lemma of S. Alexakis, this allows us to show that the Penrose Inequality is stable under small perturbations of the standard Schwarzschild null cone.
