We apply this result to multidimensional expanding maps and extend it to the realm of random dynamical systems. For random sequences, we obtain a relation between the longest common substring between multiple sequences and the generalized R\\'enyi entropy. Applications to Markov chains, Gibbs states and the stochastic scrabble are given.", "revisions": [ { "version": "v1", "updated": "2019-12-13T13:16:56.000Z" } ], "analyses": { "keywords": [ "generalized fractal dimension", "shortest distance", "multiple orbits", "gibbs states", "random dynamical systems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
