Title:The D2n planar algebras
Seminar:GAP Seminar
Speaker:Scott Morrison, Microsoft Station Q @ U.C. Santa Barbara
I'll try to give a gentle introduction to the world of "subfactor planar algebras". These are lovely topological/combinatorial gadgets, which give an alternative interpretation of the theory of subfactors. There's an "ADE" classification of the small examples, and I'll quickly focus on the type D cases. Here, I'll show how to give explicit generators and relations for the planar algebras. Perhaps at the end of the talk I'll have time to explain how to use these examples to define knot invariants, and then to obtain strange new identities between classical knot polynomials.
