多重正交多项式系综

Multiple orthogonal polynomial ensembles

Arno B. J. Kuijlaars

摘要:

多重正交多项式传统上被研究,因为它们与数论和逼近论有关。近年来,人们发现它们与随机矩阵理论中的某些模型有关。本文引入了多重正交多项式系综的概念,并导出了它们的一些基本性质。结果表明,Angelesco和Nikishin系统引起的MOP合奏,并与这些系统相关联的平衡问题有一个自然的解释的背景下,MOP合奏。

英文摘要:

Multiple orthogonal polynomials are traditionally studied because of their connections to number theory and approximation theory. In recent years they were found to be connected to certain models in random matrix theory. In this paper we introduce the notion of a multiple orthogonal polynomial ensemble (MOP ensemble) and derive some of their basic properties. It is shown that Angelesco and Nikishin systems give rise to MOP ensembles and that the equilibrium problems that are associated with these systems have a natural interpretation in the context of MOP ensembles.
