Transitive topological Markov chains of given entropy and period with or without measure of maximal entropy. (English) Zbl 1439.37013
Summary: We show that, for every positive real number \(h\) and every positive integer \(p\), there exist oriented graphs \(G, G'\) (with countably many vertices) that are strongly connected, of period \(p\), of Gurevich entropy \(h\), and such that \(G\) is positive recurrent (thus the topological Markov chain on \(G\) admits a measure of maximal entropy) and \(G'\) is transient (thus the topological Markov chain on \(G'\) admits no measure of maximal entropy).
