Venue: 
INI Seminar Room 1
Abstract: 

This is a review, beginning with examples of how to express various combinatorial problems, including self-avoiding walks and loops in graphs, in terms of Gaussian integrals. The second half will be a review of techniques such as tree graph formulas for approximating the resulting integrals.
