Matrix integrals and Feynman diagrams in the Kontsevich model
D. Fiorenza
R. Murri
Abstrak
We review some relations occurring between the combinatorial intersection theory on the moduli spaces of stable curves and the asymptotic behavior of the ’t Hooft-Kontsevich matrix integrals. In particular, we give an alternative proof of the Witten-Di Francesco-ItzyksonZuber theorem —which expresses derivatives of the partition function of intersection numbers as matrix integrals— using techniques based on diagrammatic calculus and combinatorial relations among intersection numbers. These techniques extend to a more general interaction potential. e-print archive: http://lanl.arXiv.org/abs/math.AG/0111082 528 MATRIX INTEGRALS AND FEYNMAN DIAGRAMS. . .
