关于二维量子引力的三种方法的一点注记

A remark on the three approaches to 2D Quantum gravity

A. Belavin, M. Bershtein, G. Tarnopolsky

摘要:

考虑单矩阵模型。定义了关联数的母函数,使其与刘维尔引力的母函数一致。利用Kontsevich定理,我们解释了这个生成函数是拓扑引力生成函数的解析延拓。我们检验了$p$ -临界矩阵模型中关联函数的拓扑递归关系。

英文摘要:

The one-matrix model is considered. The generating function of the correlation numbers is defined in such a way that this function coincide with the generating function of the Liouville gravity. Using the Kontsevich theorem we explain that this generating function is an analytic continuation of the generating function of the Topological gravity. We check the topological recursion relations for the correlation functions in the $p$-critical Matrix model.
