Amenable groups and cellular automata
Annales de l'Institut Fourier, Tome 49 (1999) no. 2, p. 673-685
On étend les théorèmes “Jardin d’Eden” de Moore et Myhill au cas des automates cellulaires dont l’univers est un graphe de Cayley d’un groupe finiment engendré moyennable. On obtient ainsi une extension du résultat analogue de A. Machi et F. Mignosi pour les groupes à croissance sub-exponentielle.
We show that the theorems of Moore and Myhill hold for cellular automata whose universes are Cayley graphs of amenable finitely generated groups. This extends the analogous result of A. Machi and F. Mignosi “Garden of Eden configurations for cellular automata on Cayley graphs of groups” for groups of sub-exponential growth.
