In this work, we investigate the anisotropic Bianchi type I cosmological model in the chiral set-up in a twofold manner. Firstly, we consider a quintessence plus a k-essence-like model, where two scalar fields but only one potential term is considered. Secondly, we look at a model where in addition to the two scalar fields the two potential terms are taken into account as well as the standard kinetic energy and the mixed term. Regarding this second model, it is shown that two possible cases can be studied: a quintom-like case and a quintessence-like case. In each of the models, we were able to find both classical and quantum analytical solutions.

各向异性手性宇宙学：精确解

在这项工作中，我们以双重方式研究了手性设置中的各向异性 Bianchi I 型宇宙学模型。首先，我们考虑一个精髓加上一个ķ- 类本质模型，其中两个标量场但只考虑一个潜在项。其次，我们看一个模型，其中除了两个标量场之外，还考虑了两个势项以及标准动能和混合项。关于第二个模型，表明可以研究两种可能的情况：类似quintom的情况和类似quintessence的情况。在每个模型中，我们都能找到经典和量子解析解。
