Local non-periodic order and diam-mean equicontinuity on cellular automata Article uri icon

abstract

  • Diam-mean equicontinuity is a dynamical property that has been of use in the study of non-periodic order. Using some type of ‘local’ skew product between a shift and an odometer looking cellular automaton (CA), we will show that there exists an almost diam-mean equicontinuous CA that is not almost equicontinuous (and hence not almost locally periodic). Previously, we constructed a CA that is almost mean equicontinuous [L.D.I.S. Baños and F. García-Ramos, Mean equicontinuity and mean sensitivity on cellular automata, Ergodic Theory Dynam. Systems 41 (12) (2021), pp. 3704–3721] but not almost diam-mean equicontinuous [L.D.I.S. Baños and F. García-Ramos, Diameter mean equicontinuity and cellular automata, Proceedings of the 27th International Workshop on Cellular Automata and Discrete Complex Systems, arXiv:2106.09641, 2021]. © 2022 Informa UK Limited, trading as Taylor %26 Francis Group.
