具有旋量场和viscous fluid的各向异性宇宙模型（含$Λ$项）：定性解
Anisotropic cosmological models with spinor field and viscous fluid in presence of a $Λ$ term: qualitative solutions
摘要：
研究了一类非线性旋量和Bianchi I型引力场的自洽系统，其中存在粘性流体和$Λ$项，旋量场的非线性是由双线性旋量形式$S$和$P$构成的不变量$I$和$J$的任意函数，得到了一个多参数常微分方程组\cite{saharrp,grqcnlsp} .对该系统进行了全面的定性分析。一个完整的定性分类的宇宙演化模式给出了相应的动力系统已经说明。
英文摘要：
The study of a self-consistent system of nonlinear spinor and Bianchi type I gravitational fields in presence of a viscous fluid and $Λ$ 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.
