Feynman diagrams and transition polynomial
by

Feynman diagrams arise from physics, and have interesting applications in mathematics and molecular biology. The transition polynomial for 4-regular graphs was defined by Jaeger to unify polynomials given by vertex reconfigurations similar to the skein relations of knots. It is closely related to the Kauffman bracket, Tutte polynomial, and the Penrose polynomial. This talk will discuss some natural relations between the two concepts. In particular, we show that the genus of a Feynman diagram is encoded in the transition polynomial. This is joint work with Kerry Luse.
