Maloney", "Dan Rust" ], "categories": [ "math.DS", "math.AT" ], "abstract": "We study the topology and dynamics of subshifts and tiling spaces associated to non-primitive substitutions in one dimension. We identify a property of a substitution, which we call tameness, in the presence of which most of the possible pathological behaviours of non-minimal substitutions cannot occur. We prove that a strongly aperiodic substitution is tame, and use this to prove a slightly stronger version of a result of Durand, which says that the subshift of a minimal substitution is topologically conjugate to the subshift of a primitive substitution. We then extend to the non-minimal setting a result obtained by Anderson and Putnam for primitive substitutions, which says that a substitution tiling space is homeomorphic to an inverse limit of a certain CW complex under a self-map induced by the substitution. We use this result to explore the structure of the lattice of closed invariant subspaces and quotients of a substitution tiling space, for which we compute cohomological invariants that are stronger that the \\v{C}ech cohomology of the tiling space alone.", "revisions": [ { "version": "v1", "updated": "2016-04-05T13:12:40.000Z" } ], "analyses": { "subjects": [ "37B10", "55N05", "54H20", "37B50", "52C23" ], "keywords": [ "one-dimensional substitution tiling spaces", "primitivity", "primitive substitution", "non-minimal substitutions", "slightly stronger version" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160401246M" } } }
