Relative Entropy Functions for Factor Maps between Subshifts
Let (X,S) and (Y, T ) be topological dynamical systems and π : X → Y a factor map. A function F ∈ C(X) is a compensation function for π if P (F + φ ◦ π) = P (φ) for all φ ∈ C(Y ). For a factor code between subshifts of finite type, we analyze the associated relative entropy function and give a necessary condition for the existence of saturated compensation functions. Necessary and sufficient co...
متن کاملEquilibrium States for Factor Maps between Subshifts
Let π : X → Y be a factor map, where (X,σX) and (Y, σY ) are subshifts over finite alphabets. Assume that X satisfies weak specification. Let a = (a1, a2) ∈ R with a1 > 0 and a2 ≥ 0. Let f be a continuous function on X with sufficient regularity (Hölder continuity, for instance). We show that there is a unique shift invariant measure μ on X that maximizes ∫ f dμ+ a1hμ(σX) + a2hμ◦π−1(σY ). In pa...

Let π : X → Y be a factor map, where (X,σX) and (Y, σY ) are subshifts over finite alphabets. Assume that X satisfies weak specification. Let a = (a1, a2) ∈ R 2 with a1 > 0 and a2 ≥ 0. Let f be a continuous function on X with sufficient regularity (Hölder continuity, for instance). We show that there is a unique shift invariant measure μ on X that maximizes μ(f) + a1hμ(σX) + a2hμ◦π−1(σY ). In p...
متن کاملHigher-dimensional Subshifts of Finite Type, Factor Maps and Measures of Maximal Entropy
We investigate factor maps of higher-dimensional subshifts of finite type. In particular, we are interested in how the number of ergodic measures of maximal entropy behaves under such factor maps. We show that this number is preserved under almost invertible maps, but not in general under finite to one factor maps. One of our tools, which is of independent interest, is a higher-dimensional char...
متن کاملEntropy Estimate for Maps on Forests
A 1993 result of J. Llibre, and M. Misiurewicz, (Theorem A [5]), states that if a continuous map f of a graph into itself has an s-horseshoe, then the topological entropy of f is greater than or equal to logs, that is h( f ) ? logs. Also a 1980 result of L.S. Block, J. Guckenheimer, M. Misiurewicz and L.S. Young (Lemma 1.5 [3]) states that if G is an A-graph of f then h(G) ? h( f ). In this pap...
