Ernst方程Kerr型双荷解

The Kerr Dyon Blackhole Solution of Ernst Equation

本文采用Ernst生成技术得到了一个严格的Kerr型双荷解,给出了双荷的复引力势ε、复电磁势φ和电磁场的解析表达式.当磁荷g=0时,双荷度规退化为Kerr-Newman度规,当自旋参量a=0时,度规退化为Reissner-Nordstron度规.

In this paper, by using Ernst generation method, we obtain the Kerr metric of a dyon, giving out the complex gravitati-onal potential ε, complex electromagnegnetic potential Φ and the analytic expression of the electromagnetic field of the dyon.When G=0, the metric reduces to Kerr-Newman metric, and when a=0, it reduces to the Reissner- Nordstrom metric.
