Abstract. Rule 54, in Wolfram’s notation, is one of elementary yet complexly behaving one-dimensional cellular automata. The automaton supports gliders, glider guns and other non...
In this paper, two-dimensional cellular automata as one-dimensional language recognizers are considered. Following the approach of M. Delorme and J. Mazoyer to embed one-dimensiona...
In this paper, we look at the extension of Hedlund's characterization of cellular automata to the case of cellular automata in the hyperbolic plane. This requires an addition...
