#### Garden of Eden Theorems for dynamical systems: old and new

###### Tullio Ceccherini-Silberstein (Universita' del Sannio (Benevento))

Abstract: In this talk, completely self-contained, I would like to survey the classical Garden of Eden Theorem for cellular automata with finite alphabet over the group Z^d, originally establisehd by E.F. Moore and J. Myhill in the early 1960', and its more recent generalizations (with other alphabet sets and over larger classes of groups) as well as some extensions to other dynamical systems of algebraic origin, obtained in collaboration with Michel Coornaert.
