Colored Graphs and Matrix Integrals
I. V. Artamkin Faculty of Mathematics, State University – Higher School of Economics, Moscow, Russia
Abstract:
We discuss applications of generating functions for colored graphs to asymptotic expansions of matrix integrals. The described technique provides an asymptotic expansion of the Kontsevich integral. We prove that this expansion is a refinement of the Kontsevich expansion, which is the sum over the set of classes of isomorphic ribbon graphs. This yields a proof of Kontsevich's results that is independent of the Feynman graph technique.
