Complexity of Shift Spaces on Semigroups

J. C. Ban, C. H. Chang, Y. Z. Huang

Let $G = ⟨ S ∣ R_{A} ⟩$ be a semigroup with generating set $S$ and equivalences $R_{A}$ among $S$ determined by a matrix $A$ . This paper investigates the comple…

On the topological entropy of subshifts of finite type on free semigroups

Jung-Chao Ban, Chih-Hung Chang

In this paper, we provide an effective method to compute the topological entropies of $G$ -subshifts of finite type ( $G$ -SFTs) with $G = F_{d}$ and $S_{d}$ , the free group and free se…

Topological Degree of Shift Spaces on Monoids

Jung-Chao Ban, Chih-Hung Chang, Nai-Zhu Huang

This paper considers the topological degree of $G$ -shifts of finite type for the case where $G$ is a nonabelian monoid. Whenever the Cayley graph of $G$ has a finite representation…
