最大熵测度检测非一致双曲性

The maximal entropy measure detects non-uniform hyperbolicity

Juan Rivera-Letelier

摘要:

利用极大熵测度刻画了有理映射的两个非一致双曲性条件:半双曲性和拓扑Collet-Eckmann条件.在证明这些结果的过程中,我们使用了相同的工具,推广了Carleson,Jones和Yoccoz的一个结果,即半双曲性将无穷大的吸引区域为John域的多项式映射刻画为具有完全不变吸引区域的有理映射.

英文摘要:

We characterize two of the most studied non-uniform hyperbolicity conditions for rational maps, semi-hyperbolicity and the topological Collet-Eckmann condition, in terms of the maximal entropy measure. Using the same tools in the proof of these results we give an extension of a result of Carleson, Jones and Yoccoz, that semi-hyperbolicity characterizes those polynomial maps whose basin of attraction of infinity is a John domain, to rational maps having a completely invariant attracting basin.
