最小超引力下含泡黑洞的唯一性

Uniqueness of Black Holes with Bubbles in Minimal Supergravity

Jay Armas

摘要:

推广了五维最小超引力中具有三个相互独立Killing矢量场的非极值黑洞的唯一性定理,以解释在外部连通域中非平凡2-圈的存在.我们考虑的黑洞时空可能包含多个不连通的视界,并且是渐进平坦的或渐进卡鲁扎-克莱因的。我们表明,为了唯一指定的黑洞时空,除了提供其域结构和一组渐近和本地的电荷,它是必要的测量的磁通量,支持2-圈以及通量在两个半无限旋转平面的域图。

英文摘要:

We generalise uniqueness theorems for non-extremal black holes with three mutually independent Killing vector fields in five-dimensional minimal supergravity in order to account for the existence of non-trivial 2-cycles in the domain of outer communication. The black hole space-times we consider may contain multiple disconnected horizons and be asymptotically flat or asymptotically Kaluza-Klein. We show that in order to uniquely specify the black hole space-time, besides providing its domain structure and a set of asymptotic and local charges, it is necessary to measure the magnetic fluxes that support the 2-cycles as well as fluxes in the two semi-infinite rotation planes of the domain diagram.
