平面上全纯抛物芽的一个拓扑特征

A topological characterisation of holomorphic parabolic germs in the plane

Frédéric Le Roux

摘要:

Gambaudo和Pécou在他们的论文“A拓扑不变量for volume preserving homomorphisms”(遍历论Dynam. Systems 15(1995),no.3,535- 541)。本文证明了Gambaudo-Pécou性质的否定刻画了全纯抛物芽的拓扑动力学。因此,可以定义曲面同胚的芽围绕一个不动点的旋转集,并且除了可数个共轭类之外,它将是非平凡的。

英文摘要:

Gambaudo and Pécou introduced the ``linking property'' to study the dynamics of germs of planar homeomorphims and provide a new proof of Naishul theorem in their paper "A topological invariant for volume preserving diffeomorphisms" (Ergodic Theory Dynam. Systems 15 (1995), no. 3, 535--541). In this paper we prove that the negation of Gambaudo-Pécou property characterises the topological dynamics of holomorphic parabolic germs. As a consequence, a rotation set for germs of surface homeomorphisms around a fixed point can be defined, and it will turn out to be non trivial except for countably many conjugacy classes.
