测量覆盖的理论熵

Measure theoretical entropy of covers

Uri Shapira

摘要:

本文在测度论动力系统中引入了可测覆盖U的测度论熵的三个概念。其中两个已经在[R]中引入,新的一个只定义在遍历的情况下。然后我们证明这三个概念是一致的,从而回答了[R]中提出的一个问题,并恢复了一个变分不等式(在[GW]中证明)和经典的变分原理的证明基于覆盖和划分的熵之间的比较。

英文摘要:

In this paper we introduce three notions of measure theoretical entropy of a measurable cover U in a measure theoretical dynamical system. Two of them were already introduced in [R] and the new one is defined only in the ergodic case. We then prove that these three notions coincide, thus answering a question posed in [R] and recover a variational inequality (proved in [GW]) and a proof of the classical variational principle based on a comparison between the entropies of covers and partitions.
