摘要
分析了一类余维二向量场的分岔过程 首先基于系统的规范型,得到了不同的定常解,然后针对不同的分岔解运用稳定性判据,分别确定其稳定性条件,在参数平面上定义了临界曲线 于是就将参数空间划分为不同的区域,不同的区域和不同的分岔解相对应,由此给出了该系统3 D解存在的必要条件及证明 继而根据不同的情形。
The bifurcation behavior of vector field associated with codimension 2 is discussed. At first, based on the normal forms of the system, different steady state solutions are obtained. By applying the stability criteria to determine the stable conditions of respective bifurcation solutions, we define the critical curves on the parameter plane. The parameter subspace is divided into different regions according to different solutions. Then we verify the existing necessary conditions of 3D solutions. In the end the transition boundaries corresponding to different cases are sought.
