S-Expansiveness and Zip Shift Maps in Symbolic Dynamics (2510.12980v1)
Published 14 Oct 2025 in math.DS and nlin.CD
Abstract: In this paper, we introduce the concept of S-expansiveness for local homeomorphisms and demonstrate that a class of extended symbolic dynamics, known as zip shift maps, are S-expansive and possess the shadowing property. Furthermore, we prove that any S-expansive local homeomorphism is a factor of a zip shift map.
