A C*-algebra is residually finite-dimensional (RFD) if it has a separating family of finite-dimensional representations. The property of a C*-algebra of being RFD is central in C*-algebra theory and has connections with other important notions and problems.

The topic of this talk will be the RFD property in dynamical context, namely we will discuss the RFD property of crossed products by amenable actions and of C*-algebras of amenable etale groupoids. We will present consequences of our results to residual properties of groups and to approximations of representations in spirit of Exel and Loring, and we will discuss examples.

Joint work with Adam Skalski.
