摘要
We prove that D a parts per thousand yen 5 dimensional stationary, non-static near-horizon geometries with (D-3) commuting rotational symmetries subject to the vacuum Einstein equations including a cosmological constant cannot have toroidal horizon topology. In D = 4 dimensions, the same result is obtained under the assumption of a non-negative cosmological constant.
