摘要

我们在修正的f （R， T）引力理论的框架下考虑带畴壁的Bianchi - vi0型时空。为了求解场方程，我们假设剪切标量σ与膨胀标量θ成正比。本文还考虑了正压流体状态参数方程的参数化，并讨论了其对畴壁的影响。已经观察到，畴壁可能表现得像暗能量。对一些物理参数也进行了详细的讨论。

Domain Wall Bianchi Type VI0 Universe in f(R, T) Gravity

We consider the Bianchi type-VI₀ space time with domain walls in the framework of the modified f (R, T) theory of gravitation. To solve the field equations, we assume that the shear scalar σ is proportional to the expansion scalar θ. We also consider the parametrization of the equation of the state parameter of barotropic fluid and discuss the effect on domain walls. It has been observed that the domain wall may behave like dark energy. Some physical parameters are also discussed in detail.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
