Measures of maximal entropy
We extend the results of Walters on the uniqueness of invariant measures with maximal entropy on compact groups to an arbitrary locally compact group. We show that the maximal entropy is attained at the left Haar measure and the measure of maximal entropy is unique.
متن کاملMeasures of Maximal Relative Entropy
Given an irreducible subshift of finite type X , a subshift Y , a factor map π : X → Y , and an ergodic invariant measure ν on Y , there can exist more than one ergodic measure on X which projects to ν and has maximal entropy among all measures in the fiber, but there is an explicit bound on the number of such maximal entropy preimages.
متن کاملMaximal-entropy random walk unifies centrality measures
This paper compares a number of centrality measures and several (dis-)similarity matrices with which they can be defined. These matrices, which are used among others in community detection methods, represent quantities connected to enumeration of paths on a graph and to random walks. Relationships between some of these matrices are derived in the paper. These relationships are inherited by the ...
متن کاملMaximal entropy measures for Viana maps
In this note we construct measures of maximal entropy for a certain class of maps with critical points. The main application of our result is the existence of measures of maximal entropy for the so-called Viana maps.
متن کاملMeasures of Maximal Entropy for Random Β-expansions
Let β > 1 be a non-integer. We consider β-expansions of the form ∑∞ i=1 di βi , where the digits (di)i≥1 are generated by means of a random map Kβ defined on {0, 1}N× [0, bβc/(β − 1)]. We show that Kβ has a unique measure νβ of maximal entropy log(1 + bβc). Under this measure, the digits (di)i≥1 form a uniform Bernoulli process, and the projection of this measure on the second coordinate is an ...
