我们提出了一种新的超对称的、渐近平坦的、在透镜空间拓扑视界内外有规则的五维超引力的黑洞解。该解具有7个独立参数，并提升为IIB型超重力的超对称D1-D5-P黑膜解族。解耦极限是渐近的，其近视界几何是极值Bañados-Teitelboim-Zanelli黑洞的近视界几何的扭曲积，尽管它不是（局部）体中的积空间。我们证明了一种特殊情况下黑透镜的解耦极限与黑环的解耦极限通过谱流相联系，从而提供了其熵的解释。也给出了超重力的类似解。
We present a new supersymmetric, asymptotically flat, black hole solution to five-dimensionalsupergravity which is regular on and outside an event horizon of lens space topology. The solution has seven independent parameters and uplifts to a family of-supersymmetric D1-D5-P black brane solutions to type IIB supergravity. The decoupling limit is asymptotically, with a near-horizon geometry that is a twisted product of the near-horizon geometry of the extremal Bañados-Teitelboim-Zanelli black hole and, although it is not (locally) a product space in the bulk. We show that the decoupling limit of a special case of the black lens is related to that of a black ring by spectral flow, thereby supplying an account of its entropy. Analogous solutions ofsupergravity are also presented.
