多参数等变分歧问题的强接触等价

Strongly Contact Equivalence of Equivariant Bifurcation Problems with Multiparameter

在什么条件下两个分歧问题关于某一等价群而言是等价的，这在分歧理论研究中是很有意义的．文章对多参数等变分歧问题的强接触等价提供了两个充分条件，推广了文献［１。

An interesting problem in the study of bifurcation theory is to determine when two bifurcation problems are equivalent with respect to some group of equivalences. This paper gives two sufficient conditions for two equivariant bifurcation problems with multiparameter to be strongly contact equivalent.The results obtained in the paper generalize related results in references.
