在电宇宙中的二类黑洞的外部度规场和电磁场的严格解

Two Kinds of Black Holes in an Electric Universe

运用Ernst方程内部对称群的Harrison变换 ,得到了E -M场方程的二个新的严格解 ,发现在电宇宙中的R -N度规仍是静态的 ,这与磁宇宙的结果不同。

The internal symmetry groups was found by Kinnersley in the Ernsts equation,In this paper we adopted the Harrisons transformation in groups and obtained exact expressions for the exterior metric field associated with Schwarzschild and Reissner-Nordstrom black holes in an electric universe.There is an arbitrary parameter E 0 in the expressions,it expresses a uniform electric field in the direction opposite to the polar axis.We found that the R-N metric form in an electric universe is static, and it is different from the metric form in a magnetic universe.
