单中心和双中心极值黑洞的对称性

On Symmetries of Extremal Black Holes with One and Two Centers

Sergio Ferrara, Alessio Marrani

摘要:

在简要介绍吸引子机制之后,我们回顾了E7型群在局部超对称引力理论中作为广义电磁对偶对称性的出现,特别强调了具有一个或两个中心的极端黑洞解背景下通量的辛结构。在后一种情况下,一个“水平”对称SL(2,R)的作用是阐明提出了一组两个中心的关系,两个中心不变多项式的结构。

英文摘要:

After a brief introduction to the Attractor Mechanism, we review the appearance of groups of type E7 as generalized electric-magnetic duality symmetries in locally supersymmetric theories of gravity, with particular emphasis on the symplectic structure of fluxes in the background of extremal black hole solutions, with one or two centers. In the latter case, the role of an "horizontal" symmetry SL(2,R) is elucidated by presenting a set of two-centered relations governing the structure of two-centered invariant polynomials.
