ABSTRACT: In this talk I would like to introduce the audience to the
theory of cellular automata and groups focusing on some dynamical 
aspects
of infinite groups (amenability, residual finiteness, local 
finiteness,periodicity,
surjunctivity and soficity). As an application, we shall also describe 
a solution
to the Kaplansky conjecture on the stable finiteness of groups rings 
(with
coefficients in any field) for the class of sofic groups.
