## Probabilistic Operator Algebra Seminar: Non-amenable, hyperfinite subfactors

Seminar | March 5 | 2-4 p.m. | 736 Evans Hall

Dietmar Bisch, Vanderbilt University

Department of Mathematics

I will present constructions of hyperfinite subfactors with infinite representation theory that cannot be recovered from their standard invariant. While it is open how to distinguish such non-amenable subfactors in general, some invariants are known and will be discussed. I hope to convince you that the world of non-amenable, hyperfinite subfactors is extremely interesting.
