左右等价群下分歧参数带有对称性的等变分歧问题开折的无穷小稳定性
Infinitesimal Stability of Unfolding of Equivariant Bifurcation Problems with Parameter Symmetry Under Left-Right Equivalence Group
【摘要】 基于奇点理论中光滑映射芽的左右等价关系,讨论分歧参数带有对称性的等变分歧问题开折的稳定性,刻画了无穷小稳定开折的特征,并指出该类等变分歧问题关于左右等价而言的通用开折必为无穷小稳定开折.
【Abstract】 Based on left-right equivalence of smooth map-germs in singularity theory, the stability of unfolding of equivariant bifurcation problems is discussed and infinitesimally stable unfolding is characterized. It is pointed that the versal unfolding of such a bifurcation problem as mentioned above must be infinitesimally stable.
