高维中的收缩刚性芽
Contracting rigid germs in higher dimensions
摘要:
在Favre之后,我们定义了一个全纯芽f:(C ^d,0)->(C ^d,0)是刚性的,如果所有迭代的临界集的并有简单的正规交叉奇点.本文给出了任意维到全纯共轭的收缩刚性芽的部分分类。有趣的是,我们发现了新的共振现象,涉及的微分f和它的线性作用的基本群的补充的临界集。
英文摘要:
Following Favre, we define a holomorphic germ f:(C^d,0) -> (C^d,0) to be rigid if the union of the critical set of all iterates has simple normal crossing singularities. We give a partial classification of contracting rigid germs in arbitrary dimensions up to holomorphic conjugacy. Interestingly enough, we find new resonance phenomena involving the differential of f and its linear action on the fundamental group of the complement of the critical set.
