Topology Seminar: Dave Penneys (University of Toronto), 'Constructing subfactors with jellyfish'

Event Date: 

Tuesday, November 13, 2012 - 3:30pm to 4:30pm

Event Location: 

  • 4607B South Hall

I will start with a basic introduction to planar algebras. I will then discuss recent joint work with Scott Morrison (arXiv:1208.3637) and recent joint work with Stephen Bigelow (arXiv:1208:1564). With Morrison, we construct a new exotic subfactor planar algebra using Bigelow's jellyfish algorithm. With Bigelow, we determine exactly when a planar algebra has a presentation by generators and jellyfish relations.
