Positive mass theorem for initial data sets with corners along a hypersurface

Abstract

We prove positive mass theorem with angular momentum and charges for axially symmetric, simply connected, maximal, complete initial data sets with two ends, one designated asymptotically flat and the other either (Kaluza-Klein) asymptotically flat or asymptotically cylindrical, for 4-dimensional Einstein-Maxwell theory and 5-dimensional minimal supergravity theory which metrics fail to be C 1 and second fundamental forms and electromagnetic fields fail to be C 0 across an axially symmetric hypersurface Σ. Furthermore, we remove the completeness and simple connectivity assumptions in this result and prove it for manifold with boundary such that the mean curvature of the boundary is non-positive.

“…Similar results were also proved by Shi and Tam using Witten's spinor method together with an application to the proof of the positivity of the Brown-York quasi-local mass [17], and by McFeron and Szkelyhidi using the Ricci flow method [12]. Recently, Alaee and Yau provided the positive mass theorem with angular momentum and charges for axially symmetric initial data sets with corners along a hypersurface [1]. When metrics have lowdimensional singular sets, Lee also used the conformal deformation method to proved the theorem [7].…”
