Auti-de Sitter时空的事件视界

Event Horizons of Auti-de Sitter Space-time

通过运用零曲面方程,得到了Auti-deSitter时空事件视界方程,研究了方程的解析解,并利用计算机软件,确定Auti-deSitter时空事件视界位置.结果表明,与deSitter时空不同,Auti-deSitter时空只有黑洞外事件视界和黑洞内事件视界两个事件视界,而没有宇宙事件视界.

The event horizon equation of the Auti-de Sitter space-time is obtained.Analytic solutions of the equation are investigated.The positions of the event horizon of the Auti-de Sitter space-time are ascertained by using computer softwares.The results show that the Auti-de Sitter is different form de Sitter space-time.There are inner and outer black hole horizons in the Auti-de Sitter space-time ,but no cosmological horizon.
