Noncompact Fill-Ins of Bartnik Data

Dan A. Lee, Martin Lesourd, Ryan Unger

We generalize Y. Shi and L.-F.\ Tam's \cite{ShiTam} nonnegativity result for the Brown-York mass, by considering nonnegative scalar curvature (NNSC) fill-ins that need only be comp…

Gravitational collapse to extremal black holes and the third law of black hole thermodynamics

Christoph Kehle, Ryan Unger

We construct examples of black hole formation from regular, one-ended asymptotically flat Cauchy data for the Einstein-Maxwell-charged scalar field system in spherical symmetry whi…

Density and positive mass theorems for incomplete manifolds

Dan A. Lee, Martin Lesourd, Ryan Unger

For manifolds with a distinguished asymptotically flat end, we prove a density theorem which produces harmonic asymptotics on the distinguished end, while allowing for points of in…
