摘要
利用奇点理论方法讨论了加权观点下的分歧问题,提出了带有非孤立分歧点的分歧问题的Σ-C^(0)-BD等价关系,给出了分歧问题在Σ-C^(0)-BD等价下分歧问题的Σ-C^(0)-BD有限决定的一个解析几何的非退化判别条件,推广了已有结果.
Under theΣ-C^(0)-BD equivalence on bifurcation problems,theΣ-C^(0)-BD finite determination of bifurcation problems from the weighted point view is being discussed.Some criteria on theΣ-C^(0)-BD finite determination of bifurcation problems is then obtained in terms of an analytic-geometric nondegeneracy condition,which generalize the result on the C^(0)finite determination of bifurcation problems.
