## Infinite depth subfactors

##### Abstract:

A subfactor has infinite depth if its standard representation generates infinitely many irreducibles. Such subfactors are hard to construct and only very few methods are known to produce examples with non-integer Jones index. We will explain one such procedure, which involves a notion of free product for the associated planar algebras (joint work with Vaughan Jones).
