摘要
本文研究了广义相对论中具有线性状态方程(EoS) p = αρ−β的各向异性齐次Bianchi型宇宙学模型，其中α和β为常数。为了得到场方程的解，我们假定了展开标量θ与剪切标量σ成正比的几何限制。模型的几何和物理方面也进行了研究。
Bianchi type-II universe with linear equation of state
We have studied anisotropic and homogeneous Bianchi type-II cosmological model with linear equation of state (EoS) p = αρ−β, where α and β are constants, in General Relativity. In order to obtain the solutions of the field equations we have assumed the geometrical restriction that expansion scalar θ is proportional to shear scalar σ. The geometrical and physical aspects of the model are also studied.
