Title: B-free systems and their automorphisms

Abstract: I plan to start with a brief introduction to B-free dynamical systems (derived from B-free numbers like e.g. the square-free ones). After a short description of the range of dynamical possibilities of these systems, I will concentrate on the two  extreme ends of this range, namely on those B-free systems which are "as chaotic as possible" (like the square-free system),and those which are "as close to being periodic as possible" (regular Toeplitz systems). For these two classes of topological  dynamical systems I will report about recent and ongoing progress in understanding the automorphism group of the systems.
