Interactions between operator algebras, dynamical systems and group theory
There is a long tradition of interactions between operator algebras, dynamical systems and group theory, which produced spectacular results, for example in the context of notions of orbit equivalence or measured group theory.
Our interests related to this topic include Cartan subalgebras in C*-algebras, topological groupoids, notions of orbit equivalence, self-similarity, tilings, topological full groups and rigidity phenomena.
