论文摘要
我们研究了空间平坦的Friedmann-lema \^ıtre-Robertson--Walker几何形状和标量 - 转化理论中的宇宙动力学，其中非微小耦合的标量场是一个复杂的场。我们得出宇宙磁场方程，并利用无量纲变量来确定固定点并确定其稳定性。讨论了固定点的物理特性，而我们发现两种不同的理论，标量调整和标量 - 转向理论，就背景空间中物理变量的演变而言，共享许多共同特征。
We investigate the cosmological dynamics in a spatially flat Friedmann--Lema\^ıtre--Robertson--Walker geometry in scalar-tensor and scalar-torsion theories where the nonminimally coupled scalar field is a complex field. We derive the cosmological field equations and we make use of dimensionless variables in order to determine the stationary points and determine their stability properties. The physical properties of the stationary points are discussed while we find that the two-different theories, scalar-tensor and scalar-torsion theories, share many common features in terms of the evolution of the physical variables in the background space.
