研究带有整体单极Reissner-Nordstrom de Sitter黑洞视界表面引力的几种方法

Investigation Methods of the Event Horizon Surface Gravity to Reissner-Nordstrom de Sitter Black Hole with a Global Monopole

在带有整体单极的Re issner-Nordstrom de S itter时空中,准确给出了黑洞的内外视界及宇宙视界的位置,分别用4种方法研究了该黑洞的视界表面引力,给出了相同的结论.

In Reissner-Nordstrom black hole with a global monopole in the background of de Sitter spacetime, the accurate locations of the black hole＇s inner horizon, outer horizon and cosmological horizon are shown. The horizon surface gravity of the black hole has been investigated through studying the definition of the horizon surface gravity, Klein-Gordon equation, Hamihon-Jacobi equation and Dirac equation. It is the same result of the event horizon surface of the black hole by using four methods.
