具有时空依赖状态方程的虫洞

Wormholes with a space- and time-dependent equation of state

Peter K. F. Kuhfittig

摘要:

宇宙正在加速膨胀的发现表明存在一个不断演化的状态方程。本文讨论了球对称时空中的各种虫孔解,其中状态方程是空间和时间相关的。所得解是精确的,推广了先前关于虚能支持的静态虫洞的结果。

英文摘要:

The discovery that the Universe is undergoing an accelerated expansion has suggested the existence of an evolving equation of state. This paper discusses various wormhole solutions in a spherically symmetric spacetime with an equation of state that is both space and time dependent. The solutions obtained are exact and generalize earlier results on static wormholes supported by phantom energy.
