在五维最小超引力中，视界外存在具有非平凡拓扑的球状黑洞，它们在无穷远处具有与BMPV解相同的守恒电荷。我们证明了这些黑洞中的一些比BMPV解具有更大的熵。这些时空都是渐近平坦、稳定和超对称的。我们还证明了存在一个极限，在这个极限中，黑洞收缩到零大小，解变成一个非奇异的“起泡”几何。因此，这些解为在孤子内部放置黑洞提供了明确的解析例子。
In five-dimensional minimal supergravity, there are spherical black holes with nontrivial topology outside the horizon which have the same conserved charges at infinity as the BMPV solution. We show that some of these black holes have greater entropy than the BMPV solution. These spacetimes are all asymptotically flat, stationary, and supersymmetric. We also show that there is a limit in which the black hole shrinks to zero size and the solution becomes a nonsingular “bubbling” geometry. Thus, these solutions provide explicit analytic examples of placing black holes inside solitons.
