We are building a cosmological model that has small anisotropy and curvature. For this purpose, the Bianchi type-V (BV) model with dark matter (DM) and anisotropic dark energy (DE) is considered. Assuming a law for deviation from the equation of state (Eos) of DE is linear, we study the transition from decelerated to late accelerated expansion of the Universe. In the proposed model, the linear interaction of the two components alleviates the coincidence problem of the present Universe. Examples of model parameter values compatible with observational data are given.

Bianchi type-V模型范围内的暗区相互作用

我们正在建立一个各向异性和曲率小的宇宙学模型。为此，考虑了具有暗物质 (DM) 和各向异性暗能量 (DE) 的 Bianchi V 型 (BV) 模型。假设偏离 DE 状态方程 (Eos) 的定律是线性的，我们研究了宇宙从减速膨胀到后期加速膨胀的过渡。在所提出的模型中，两个分量的线性相互作用缓解了当前宇宙的重合问题。给出了与观测数据兼容的模型参数值的例子。
