On the asymptotic measure of periodic subsystems of finite type in symbolic dynamics

J. -R. Chazottes, Z. Coelho, P. Collet

Let $Δ\subsetneq\V$ be a proper subset of the vertices $\V$ of the defining graph of an aperiodic shift of finite type $({\Sigma }_A^{+},\S )$. Let ${\Delta }_n$ be the union of cylinders in $Σ_…
