(C^2,0)中解析同态的芽群

Groups of germs of analytic diffeomorphisms in (C^2,0)

Fabio Enrique Brochero Martinez

摘要:

设G是(C^2,0)中解析同态的芽群.在G是有限的、可线性化的、阿贝尔幂零的和可解的假设下,我们发现了一些显著的性质。特别地,如果群是阿贝尔群并且有一个泛双临界群同态,则群是一个1-参数群的子群。此外,我们还研究了双临界同态轨道的拓扑性质。最后,我们找到了一些不变量,以便知道什么时候两个复同态是形式共轭的。

英文摘要:

Let G a group of germs of analytic diffeomorphisms in (C^2,0). We find some remarkable properties supposing that G is finite, linearizable, abelian nilpotent and solvable. In particular, if the group is abelian and has a generic dicritic diffeomorphisms, then the group is a subgroup of a 1-parametric group. In addition, we study the topological behaviour of the orbits of a dicritic diffeomorphisms. Last, we find some invariants in order to know when two diffeomorphisms are formally conjugates.
