# Algebra Seminar: Bar-Natan -- Some Feynman Diagrams in Algebra

Dror Bar-Natan (University of Toronto)

Wednesday 2 October, 12-1pm, Place: Carslaw 375

Some Feynman Diagrams in Algebra I will explain how the computation of compositions of
maps of a certain natural class, from one polynomial ring into another, naturally leads
to a certain composition operation of quadratics and to Feynman diagrams.  Possibly in a
later seminar I will explain how this technology can be used to construct a tangle
invariant whose need will be explained in a talk I will be giving in the topology
seminar on Sep 16.
