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 55-dimensional minimal supergravity theory which metrics fail to be C1C^1 and second fundamental forms and electromagnetic fields fail to be C0C^0 across an axially symmetric hypersurface Σ\Sigma. 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.
