圆周自映射的ω-极限集

ω-LIMIT SET FOR MAPS OF THE CIRCLE

对圆周自映射f,本文得到了如下结果:如果P(f)≠Φ,(?)x∈W (f)-P (f),则ω(x)是一个无限的极小集,同时得到了如下推论:如果P(f)≠Φ,则(?)=(?)。

For Continuous maps f of the circle to itself, We show the following results:Theorem If P (f)≠Φ. and x∈, then ω (x) is an infinite minimal set.Corollary If P (f)≠Φ. then
