局部旋转集是一个间隔

The Local Rotation Set is an Interval

Jonathan Conejeros

摘要:

设$Homeo\_0 (R 2 ; 0)$是平面上所有同胚的集合,这些同胚与单位元同素且固定0。最近在文章题为"L '系综旋转本地autour德' un点" Fr {é} d {é} ric Le Roux给出了定义的本地旋转集的一个合痕在$Homeo\_0 (R 2 ; 0)$从身份同胚f和他问,如果这一套总是一个区间。在这篇文章中,我们给出了一个肯定的答案,这个问题和类似的问题的情况下,开放的环。

英文摘要:

Let $Homeo\_0 (R 2 ; 0)$ be the set of all homeomorphisms of the plane isotopic to the identity and which fix 0. Recently in the article entitled "L'ensemble de rotation local autour d'un point fixe" Fr{é}d{é}ric Le Roux gave the definition of the local rotation set of an isotopy in $Homeo\_0 (R 2 ; 0)$ from the identity to a homeomorphism f and he asked if this set is always an interval. In this article we give a positive answers to this question and to the analogous question in the case of the open annulus.
