标题： Anisotropic cosmological models with spinor field and viscous fluid in presence of a $Λ$ term: qualitative solutions

摘要： 研究在存在粘性流体和$\Lambda$项的情况下，非线性旋量和 Bianchi 类 I 引力场的自洽系统，其中旋量场的非线性性是从双线性旋量形式$S$和$P$构造出的不变量$I$和$J$的任意函数，生成了一个多参数的常微分方程系统\cite{saharrp,grqcnlsp}。对该系统进行了彻底的定性分析。对应动力系统的宇宙演化模式的完整定性分类已被说明。 显示英文摘要

摘要： The study of a self-consistent system of nonlinear spinor and Bianchi type I gravitational fields in presence of a viscous fluid and $\Lambda$ term with the spinor field nonlinearity being some arbitrary functions of the invariants $I$ an $J$ constructed from bilinear spinor forms $S$ and $P$, generates a multi-parametric system of ordinary differential equations \cite{saharrp,grqcnlsp}. A qualitative analysis of the system in question has been thoroughly carried out. A complete qualitative classification of the mode of evolution of the universe given by the corresponding dynamic system has been illustrated.
