摘要:

利用奇点理论方法, 通过引入分歧问题对的双接触等价概念, 给出了两个分歧问题对之间双接触等价的充要条件, 并借助代数条件, 得到分歧问题对的双接触有限决定性的若干判定准则.

关键词: 双接触等价, 双接触有限决定性, 切空间,

Abstract:

In this paper, bi-contact equivalence about pairs of bifurcation problems is introduced by singularity-theoretic techniques. A sufficient and necessary condition for bi-contact equivalence between two pairs of bifurcation problems is given. Some criteria about bi-contact finite determination of pair of bifurcation problems are then obtained in terms of an algebraic condition.

Key words: bi-contact equivalence, bi-contact finite determinacy, tangent space, module
