论文摘要
我们介绍了在紧凑型公制空间上的封闭关系的回报，分散和良好的集合的概念，然后我们使用它们来获得非平凡的足够条件，以使这种关系具有非零熵。此外，我们从Li-Yorke和DC2-Chaos方面给出了有限关系与非零熵的表征。
We introduce the notions of returns, dispersions and well-aligned sets for closed relations on compact metric spaces and then we use them to obtain non-trivial sufficient conditions for such a relation to have non-zero entropy. In addition, we give a characterization of finite relations with non-zero entropy in terms of Li-Yorke and DC2-chaos.
