Some Feynman Diagrams in Algebra

University of Sydney Algebra Seminar, October 2, 2019

Abstract. 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 was explained in a talk I gave in the topology seminar on Sep 16.
