J'associe un nouveau type d'intégrales matricielles super-symétriques avec une solution arbitraire de l'équation noncommutative de Batalin–Vilkovisky. Le cas le plus simple est une extension super-symétrique du modèle de Kontsevich de la gravité 2-dimensionnelle.

I study the new type of supersymmetric matrix models associated with any solution to the quantum master equation of the noncommutative Batalin–Vilkovisky geometry. The asymptotic expansion of the matrix integrals gives homology classes in the Kontsevich compactification of the moduli spaces, which I associated with the solutions to the quantum master equation in my previous paper. I associate with the Bernstein–Leites matrix superalgebra equipped with an odd differentiation, whose square is nonzero, the family of cohomology classes of the compactification. This family is the generating function for the products of the tautological classes. The simplest example of my matrix integrals in the case of dimension zero is a supersymmetric extension of the Kontsevich model of 2-dimensional gravity.
