Stem and topological entropy on Cayley trees
Jung-Chao Ban, Chih-Hung Chang, Yu-Liang Wu +1
We consider the existence of the topological entropy of shift spaces on a finitely generated semigroup whose Cayley graph is a tree. The considered semigroups include free groups.…

Characterization and Topological Behavior of Homomorphism Tree-Shifts
Jung-Chao Ban, Chih-Hung Chang, Wen-Guei Hu +2
The purpose of this article is twofold. On one hand, we reveal the equivalence of shift of finite type between a one-sided shift and its associated hom tree-shift $\mathcal{T}_…
