论文摘要
我们对各向异性Rastall宇宙学，尤其是Kantowski-Sachs进行动态分析，局部旋转对称（LRS）Bianchi I和LRS Bianchi III宇宙学。使用动力学系统技术，对宇宙方程的定性分析产生了在物理上有趣的病例，这些案例与诸如保姆，加速，稳定的吸引子等观测值一致。详细讨论了各向同性和宇宙反弹之类的功能。
We perform dynamical analysis of anisotropic Rastall cosmologies and, in particular Kantowski-Sachs, locally rotationally symmetric (LRS) Bianchi I and LRS Bianchi III cosmologies. Using dynamical system techniques, a qualitative analysis of cosmological equations yield physically interesting cases which are in agreement with observations such as de Sitter, accelerating, stable attractors are isotropic. Features such as isotropization and cosmological bounce are discussed in detail.
