Riemannian Penrose inequality via Nonlinear Potential Theory
arXiv:2205.11642
Abstract
We provide a new proof of the Riemannian Penrose inequality for time-symmetric asymptotically flat initial data with a single black-hole horizon. The proof proceeds through a newly established monotonicity formula holding along the level sets of the -capacitary potential of the horizon boundary, in any asymptotically flat -manifold with nonnegative scalar curvature.
