Riemannian Penrose Inequality for Manifolds with Corners via Non-Linear Potential Theory

Virginia Agostiniani, Christina Karapiperi, Lorenzo Mazzieri

We present a new proof of the Positive Mass Theorem and the Riemannian Penrose Inequality for three-dimensional asymptotically flat Riemannian manifolds whose metrics fail to be $C…

Mass-type invariants in the presence of a cosmological constant

Virginia Agostiniani, Stefano Borghini, Lorenzo Mazzieri

In this paper, we introduce a new family of mass-type invariants for time-symmetric initial data in space-times satisfying the Dominant Energy Condition. For positive cosmological…

On the Serrin problem for ring-shaped domains: the -dimensional case

Virginia Agostiniani, Chiara Bernardini, Stefano Borghini +1

We provide several characterizations of ring-shaped rotationally symmetric solutions to the Serrin problem in arbitrary dimensions.

Riemannian Penrose inequality via Nonlinear Potential Theory

Virginia Agostiniani, Carlo Mantegazza, Lorenzo Mazzieri +1

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…

On the Isoperimetric Riemannian Penrose Inequality

Luca Benatti, Mattia Fogagnolo, Lorenzo Mazzieri

We prove that the Riemannian Penrose Inequality holds for Asymptotically Flat -manifolds with nonnegative scalar curvature and connected horizon boundary, provided the optimal d…
