具有大质量引力子的宇宙学解

Cosmological solutions with massive gravitons

Ali H. Chamseddine, Mikhail S. Volkov

摘要:

我们目前的解决方案描述空间封闭,开放,或平坦的宇宙学在最近提出的四分体制定的大规模引力理论。我们发现,引力子质量的影响相当于在爱因斯坦方程中引入了一个物质源,它可以由几种不同的物质类型组成-宇宙学项,精髓,宇宙弦气体和非相对论冷物质。

英文摘要:

We present solutions describing spatially closed, open, or flat cosmologies in the massive gravity theory within the recently proposed tetrad formulation. We find that the effect of the graviton mass is equivalent to introducing to the Einstein equations a matter source that can consist of several different matter types -- a cosmological term, quintessence, gas of cosmic strings, and non-relativistic cold matter.
