我们用超cr型三维Einstein-Weyl结构的提升给出了五维极小超重力的一类解。我们将这类描述为五维理论超对称解的最一般的近视界极限。特别地，我们推导出视界的紧化空间截面只能是伯杰球，是上的积度规
We show that a class of solutions of minimal supergravity in five dimensions is given by lifts of three-dimensional Einstein–Weyl structures of hyper-CR type. We characterise this class as most general near-horizon limits of supersymmetric solutions to the five-dimensional theory. In particular we deduce that a compact spatial section of a horizon can only be a Berger sphere, a product metric on
