We focus on the families obtained as finite products of the three-letter substitutions associated with the multidimensional continued fraction algorithms of Brun and Jacobi-Perron. Our tools consist in a reformulation of some combinatorial criteria (coincidence conditions), in terms of properties of discrete plane generation using multidimensional (dual) substitutions. We also deduce some topological and dynamical properties of the Rauzy fractals, of the underlying symbolic dynamical systems, as well as some number-theoretical properties of the associated Pisot numbers.", "revisions": [ { "version": "v2", "updated": "2014-06-26T17:20:31.000Z" } ], "analyses": { "keywords": [ "pisot substitutions", "combinatorial approach", "symbolic dynamical systems", "generic algorithmic framework", "pure discrete spectrum" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1401.0704B" } } }
