A-infinity GL(N)-equivariant matrix integrals-II. The nc-BV differential, (stable) ribbon graphs and compacti…fied moduli spaces.

Résumé

I review my previous results on the combinatorial aspects of my noncommutative Batalin-Vilkovisky formalism, related with stable ribbon graphs and compactified moduli spaces, I describe the combinatorial construction of cocycles representing products of psi-classes, arising from the asymptotic expansion of the supersymmetric extension of the matrix Airy integral
