We analyse some topological properties introduced by arXiv:1509.01355 in order to answer some of the questions raised by those authors. Moreover, we provide a method to characterize the complexity function for Markov tree-shifts; this function is used to calculate the tree entropies defined by arXiv:1712.02251 and arXiv:1509.08325. We compare both entropies in order to determine some of its properties. Finally, the characterization of the complexity function is used to calculate the entropy of all binary Markov tree-shifts over the alphabet $\\{0,1\\}$.", "revisions": [ { "version": "v1", "updated": "2023-07-11T23:49:22.000Z" } ], "analyses": { "keywords": [ "transition matrices", "complexity function", "binary markov tree-shifts", "tree entropies", "topological properties" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable" } } }
