TGAW02 - C*-algebras: classification and dynamical constructions

I will discuss new results on the ideal structure of reduced crossed products over discrete groups, as well as the ``boundary-theoretic’’ techniques that underlie these results. We obtain a complete characterization of primality and, for FC-hypercentral groups, a characterization of the ideal intersection property. This is joint work with Larissa Kroell and Camila Sehnem.
