Cellular Automata on Racks

Abstract

In this paper we initiate the study of cellular automata on racks. A rack RR is a set with a self-distributive binary operation. The rack RR acts on the set ARA^R of configurations from RR to a set AA. We define the cellular automaton on a rack RR as a continuous self-mapping of ARA^R defined from a system of local rules. The cellular automata on racks do not commute with the rack action. However, under certain conditions, the cellular automata on racks do commute with the rack action. We study the equivariant cellular automta (which commute with the rack action) on racks and prove several properties of these cellular automata including the analog of Curtis-Hedlund's theorem for cellular automata on groups.
