Abstract : This conference will gather researchers working on different topics such as combinatorics, computer science, probability, geometry, physics, quasicrystallography, ... but sharing a common interest: dynamical systems and more precisely subshifts, tilings and group actions. It will focus on algebraic and dynamical invariants such as group automorphisms, growth of symbolic complexity, Rauzy graphs, dimension groups, cohomology groups, full groups, dynamical spectrum, amenability, proximal pairs, ... With this conference we aim to spread out these invariants outside of their original domains and to deepen their connections with combinatorial and dynamical properties.
