Time: 16:30
Speaker: Travis Ens (Western) Title: "Fun with Feynman, part II: Graph Sums" Room: MC 108 Abstract: Abstract: Feynman's theorem, a fundamental mathematical tool in quantum field theory, provides a way to evaluate complicated integrals by summing over finite graphs. After exploring how to obtain this sum from an integral, we will reverse the correspondence and prove a famous result of Cayley, that the number of labelled trees with n vertices is nn−2, using known values of integrals. No physics will be needed to follow this lecture. For some background material please check out the Pizza Seminar blog http://pizzaseminaruwo.blogspot.ca/ |
