摘要

我们研究了霍恩德斯基(Horndeski)理论中的比安奇-I时空的等向化过程,其中$G_3(X,\phi)\neq 0$和$G_5=\text{const}/X$。一个全局单向电磁场与一个标量场相互作用的规律是 $f^2(\phi)F_{\mu\nu}F^{\mu\nu}$。在霍恩德斯基理论中,各向异性可以以不同的方式发展。所提出的重构方法使我们能够建立具有可接受的各向异性行为的模型。为了分析时空各向异性,我们使用了 $a_i/a$ ($i=1,2,3$)关系,其中 $a_i$ 是度量函数,$a\equiv(a_1a_2a_3)^{1/3}$。

Isotropization of the magnetic universe in the Horndeski theory with $G_3(X,\phi)$ and $G_5(X)$
We study the isotropization process of Bianchi-I space-times in the Horndeski theory with $G_3(X,\phi)\neq 0$ and $G_5=\text{const}/X$. A global unidirectional electromagnetic field interacts with a scalar field according to the law $f^2(\phi)F_{\mu\nu}F^{\mu\nu}$. In the Horndeski theory, the anisotropy can develop in different ways. The proposed reconstruction method allowed us to build models with acceptable the anisotropy behavior. To analyze space-time anisotropy, we used the relations $a_i/a$ ($i=1,2,3$), where $a_i$ are metric functions and $a\equiv(a_1a_2a_3)^{1/3}$.
