2-矩阵模型、双正交多项式、黎曼-希尔伯特问题和代数几何

The 2-matrix model, biorthogonal polynomials, Riemann-Hilbert problem, and algebraic geometry

Bertrand Eynard

摘要:

这篇预印本是我为巴黎第七大学所作的毕业论文的导言。本文是对2矩阵模型研究工作的总结。在引言中,给出了矩阵模型的三种不同且不等价的定义(收敛模型、轮廓上具有固定填充率的模型和形式模型)。然后,总结了双正交多项式所满足的微分系统的性质,特别是谱对偶和Riemann-Hilbert问题。然后,一节介绍循环方程和大N展开式的代数几何表述。然后,给出了双正交多项式渐近性的一个猜想。

英文摘要:

This preprint is the introduction of my habilitation thesis for Paris7 university. It is a sumary of a collection of works on the 2 matrix model. In an introduction, 3 different and unequivalent definitions of matrix models are given (convergent model, model with fixed filling fractions on contours, and formal model). Then, a sumary of properties of differential systems satisfied by biorthogonal polynomials, in particular spectral duality and Riemann-Hilbert problem. Then, a section on loop equations and algebraic geometry formulation of the large N expansion. Then, a conjecture for the asymptotics of biorthogonal polynomials.
