Abstract
We introduce cellular automata whose cell spaces are left-homogeneous spaces, show that their global transition functions are closed under composition, prove a uniform as well as a topological variant of the Curtis–Hedlund–Lyndon theorem, and deduce that such an automaton is invertible if and only if its global transition function is bijective. Examples of left-homogeneous spaces are spheres, Euclidean spaces, as well as hyperbolic spaces acted on by isometries; uniform tilings acted on by symmetries; vertex-transitive graphs, in particular, Cayley graphs, acted on by automorphisms; groups acting on themselves by multiplication; and integer lattices acted on by translations.
