高维黑洞的扭量理论--第一部分:理论

Twistor Theory of Higher-Dimensional Black Holes - Part I: Theory

Norman Metzner

摘要:

在四维空间中建立了约化扭量空间上的定常、轴对称、渐近平坦时空和丛之间的对应关系。将这种对应关系应用于高维例子的主要障碍是缺乏恩斯特势的高维等价物。本文将提出这样一种广义的Ernst势,指出在扭量图中哪里可以找到时空的棒结构,从而提供一种从棒结构和其他渐近数据生成高维爱因斯坦方程解的方法。一个重要的结果为研究五维的例子将是定理,涉及修补矩阵的外部半无限棒。

英文摘要:

The correspondence between stationary, axisymmetric, asymptotically flat space-times and bundles over a reduced twistor space has been established in four dimensions. The main impediment for an application of this correspondence to examples in higher dimensions has been the lack of a higher-dimensional equivalent of the Ernst potential. This article will propose such a generalized Ernst potential, point out where the rod structure of the space-time can be found in the twistor picture and thereby provide a procedure for generating solutions to the Einstein equations in higher dimensions from the rod structure and other asymptotic data. An important result for the study of five-dimensional examples will be the theorem which relates the patching matrices on the outer semi-infinite rods.
