摘要
本文研究一类三次Hamilton系统在三次扰动下的动力形态.利用向量场分支理论的方法讨论对该系统的两参数开折,并得到在参数平面原点领域的完整的分支图.进而对应分支图的每个区域给出相轨线图.
In this paper,we analyse the dynamical behavior for a class of cubic Hamiltonian systems under cubic perturbation. Using method of bifurcation theory in vector fields, we discuss the unfolding of two parameters for the systems and obtain a complete bifurcation diagram in the neighbourhood of origin for the parameter plane. Furthermore we also give the phase portraits corresponding to each region of the bifurcation diagram.
