Noncommutative Geometry Seminar - Dietmar Bisch
Title: Subfactors and Quantum Symmetries
Speaker: Dietmar Bisch (Vanderbilt University)
Abstract: The standard invariant of a subfactor is a complete invariant for amenable, hyperfinite subfactors by a theorem of Popa. It can be viewed as a group-like object and is a certain tensor category of "representations" of the subfactor. However, most hyperfinite subfactors are not amenable, and it is open how to distinguish them. I will discuss constructions of such examples and invariants for them. In particular, I will try to illustrate that a subfactor may encode "quantum symmetries" that are not captured by its standard invariant.
