Multiplicity of measures under factor codes and class degree joinings

Jisang Yoo

Given a finite-to-one factor code $π : X \to Y$ between irreducible sofic shifts and an ergodic $ν$ on $Y$ with full support, it is known that the fiber $π_{*}^{- 1} (ν)$ has at most $d…

Relative equilibrium states and class degree

Jisang Yoo

Given a factor code $π$ from a shift of finite type $X$ onto a sofic shift $Y$ , an ergodic measure $ν$ on $Y$ , and a function $V$ on $X$ with summable variation, we prove an invari…
