Abstract: In this paper, we re-examine charged Q-clouds around spherically symmetric, static black holes. In particular, we demonstrate that for fixed coupling constants two different branches of charged scalar clouds exist around Schwarzschild black holes. This… read more here.

Abstract: For asymptotically flat spacetimes, using the inverse mean curvature flow we show that any compact $$2$$-surface, $$S_0$$, whose mean curvature and its derivative for the outward direction are positive in a spacelike hypersurface with non-negative… read more here.
