Hopf分岔Bautin分岔 Z2对称规范型同调方法Hopf Bifurcation Bautin Bifurcation Z2-Symmetric Normal Form Homogical Method



By using a homogical method, we drive out computational formulae for normal forms of the Hopf and Bautin bifurcations in Z2-symmetric systems. For practical bifurcation analysis of Hopf and Bautin in a Z2-symmetric system, we can use these formulae to compute the first and the second Lyapunov coefficients, and check whether the bifurcation is degenerate. Furthermore, we can use the formulae of unfolding parameters to decide the topological structures when parameters perturb in a neighborhood of the critical values. So, we construct the relation between the parameters and the structures for Hopf and Bautin bifurcations in any Z2-symmetric systems.
