在本文中,我们引入了覆盖的两种测度理论熵的概念以及开覆盖的一种拓扑熵的概念。这些概念将可测划分的测度理论熵的经典概念推广到了可测覆盖。利用这些概念,我们证明了对于任意给定开覆盖的一个局部变分原理。
In this paper we introduce two notions of measure-theoretical entropy for covers and one notion of topological entropy for open covers. These notions extend the classical concept of measure-theoretical entropy of measurable partitions to measurable covers. Using these notions we prove a local variational principle for any given open cover.
