Covers counting via Feynman Calculus

Combinatorics 2012-04-12 v1

Abstract

Let GG be a finite group. In this paper we present a tool for counting the number of principle GG-bundles over a surface. As an application, we express (non-standard) generating functions for double Hurwitz numbers as integrals over commutative Frobenius algebras, associated with symmetric groups.
