非交换Batalin-Vilkovisky几何与矩阵积分

Noncommmutative Batalin-Vilkovisky geometry and Matrix integrals

Serguei Barannikov

摘要:

我们将这种新型的超对称矩阵模型与非对易Batalin-Vilkovisky几何的量子主方程的任何解相关联。矩阵积分的渐近展开给出了模空间的Kontsevich紧化中的同调类,我们在前一篇文章中将其与量子主方程的解联系起来。我们将奇异矩阵超代数与紧化的上同调类族联系起来,该超代数具有奇微分,其平方不为零。这个族是重言式类的乘积的生成函数。零维情形下矩阵积分的最简单例子是二维引力的Kontsevich模型的超对称扩展。

英文摘要:

We associate the new type of supersymmetric matrix models 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 we associated with the solutions to the quantum master equation in our previous paper. We associate with the queer 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 the matrix integrals in the case of dimension zero is a supersymmetric extenstion of the Kontsevich model of 2-dimensional gravity.
