Sufficient conditions for non-zero entropy of closed relations
Published online by Cambridge University Press: 15 February 2024
Abstract
We introduce the notions of returns and well-aligned sets for closed relations on compact metric spaces and then 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.
