粘性宇宙流体和非线性状态方程流体宇宙模型的状态探测器分析
Statefinder analysis of universe models with a viscous cosmic fluid and a fluid with a non-linear equation of state
摘要：
本文利用状态发现者参数形式主义分析了Brevik等人提出的一些宇宙模型。我们用可观测的量来确定先前未指定的常数。证明了具有一定非线性状态方程的流体的大爆炸宇宙模型与具有粘性流体的宇宙模型具有相同的行为。
英文摘要：
In the present article we analyze, by means of the statefinder parameter formalism, some universe models introduced by Brevik and co-workers. We determine constants that earlier were left unspecified, in terms of observable quantities. It is verified that a Big Bang universe model with a fluid having a certain non-linear equation of state behaves in the same way as a model with a viscous fluid.
