Title: Hilbert C*-modules and Morita equivalence for Σ*-algebras
Abstract: A C*-subalgebra of B(H) is called a Σ*-algebra if it is closed under limits of weakly-convergent sequences. We study an appropriate class of Hilbert C*-modules over these algebras and prove results analogous to those in the basic theory of C*-modules, W*-modules, and Morita equivalence.

Title: Classifying multiplier algebras of Nevanlinna-Pick spaces
Abstract: Multiplier algebras of Nevanlinna-Pick spaces are a class of non-selfadjoint operator algebras which have attracted considerable attention in recent years. The investigation of the classification problem for these algebras was initiated by Davidson, Ramsey and Shalit. I will report on the current state of this problem and talk about recent work which uses a somewhat different perspective on these algebras. In particular, this includes a complete classification result for a certain class of multiplier algebras. Moreover, I will talk about joint work with Martino Lupini in which we study the complexity of this classification problem from the point of view of Borel complexity theory.
