Alcides Buss (Florianopolis): Free actions of groups on separated graphs and their C*-algebras. Oberseminar C*-Algebren.

I will report on joint work with Ado Dalla Costa and Pere Ara on the study of free actions of groups on separated graphs. We prove a version of the Gross-Tucker theorem in this context and show how this can be used to describe the various C*-algebras attached to separated graphs carrying a free action. All this leads to certain Landstad-type duality theorems involving these algebras.
