Bas Jordans will give a talk with title " Random walks on discrete quantum groups: convergence to the boundary"
Abstract:For classical random walks there exist two boundaries: the Poisson boundary and the Martin boundary. The relation between these two boundaries is described by the so-called "convergence to the boundary". For random walks on discrete quantum groups both the Poisson boundary and Martin boundary are defined and a non-commutative analogue of convergence to the boundary can be formulated. However, no proof is known for a such a theorem. In the first part of the talk we will discuss the classical and quantum version of convergence to the boundary, explain how these are related and give an overview of what is known in general for the quantum case. In the second part we will discuss the boundary convergence for SUq(2) and for monoidally equivalent quantum groups.

Tobias Erhardt (Technische Universität, München) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15 November 24th.
Arnaud Brothier, Vanderbilt University (USA) will give a talk with title: Analytic properties for subfactors
I will discuss analytic properties for groups and their generalizations to subfactors, standard invariants, and certain tensor categories.
I will present a class of subfactor planar algebras that are constructed with a group acting on a bipartite graph.
I will show that if the group satisfies a given approximation property (such as amenability, Haagerup property, or weak amenability), then the subfactor planar algebra satisfies it as well.
I will exhibit an infinite family of subfactor planar algebras with non-integer index that are non-amenable, have the Haagerup property, and have the complete metric approximation property.

Alfons van Daele (Leuven) will give a talk with title: The Haar measure on quantum groups
Abstract: At this moment, there is no theory of locally compact quantum groups with axioms from which one can prove the existence of the Haar weights. In general, the existence is part of the axioms. There are however a few cases where the existence can be proven. This is true for compact quantum groups and for discrete quantum groups. We will discuss some aspects of these proofs and see which of them are useful in the general case.
