The collapsing interiors include the inhomogeneous solutions of Szekeres and of Barnes, which in turn include the Lemaitre-Tolman and the McVittie solutions. The collapse can result in toroidal or higher genus asymptotically AdS black holes.15 pages, 2 figures; v2: typos corrected, references addedGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - Theorytext
