Decomposition of infinite-to-one factor codes and uniqueness of relative equilibrium states

Jisang Yoo

We show that an arbitrary factor map $π : X \to Y$ on an irreducible subshift of finite type is a composition of a finite-to-one factor code and a class degree one factor code. Using…

Multiplicity structure of preimages of invariant measures under finite-to-one factor maps

Jisang Yoo

Given a finite-to-one factor map $π : (X, T) \to (Y, S)$ between topological dynamical systems, we look into the pushforward map $π_{*} : M (X, T) \to M (Y, T)$ between sets of invariant…
