Killing矢量和各向异性

Killing vectors and anisotropy

J. P. Krisch, E. N. Glass

摘要:

我们考虑一个行动,可以产生流体与三个不相等的应力度量与类空的Killing向量。作用中的参数与应力各向异性直接相关。场方程的作用下,应用到各向异性的宇宙膨胀和Gott-Hiscock宇宙弦的延伸。

英文摘要:

We consider an action that can generate fluids with three unequal stresses for metrics with a spacelike Killing vector. The parameters in the action are directly related to the stress anisotropies. The field equations following from the action are applied to an anisotropic cosmological expansion and an extension of the Gott-Hiscock cosmic string.
