Black Rings
reviews
This page contains reviews on Black holes in higher dimensional (D>4) space-times. In addition to black-hole horizons with topology S^n, there are possibilities of having other horizon topologies (like S^2\times S^1 -- the so called black rings) in D>4; this is prevented in D=4 where the black hole's horizon can only have the topology of S^2.
