Multidimensional cellular automata and generalization of Fekete's lemma

General Mathematics 2008-06-17 v3 Dynamical Systems

Abstract

Fekete's lemma is a well known combinatorial result on number sequences: we extend it to functions defined on dd-tuples of integers. As an application of the new variant, we show that nonsurjective dd-dimensional cellular automata are characterized by loss of arbitrarily much information on finite supports, at a growth rate greater than that of the support's boundary determined by the automaton's neighbourhood index.
