AI总结:

本文利用拟共形映射理论,建立了角域上Bergman正交多项式的强渐近性,并应用于单叶函数系数估计、算子理论、容量计算和矩重建算法。

摘要:

我们建立了定义在具有尖点的Jordan域上的Bergman正交多项式的强渐近性。这补充了T. Carleman于1923年开始的关于解析曲线边界域强渐近性的研究,以及P.K. Suetin在1960年代建立的关于光滑边界域强渐近性的工作。为此,我们采用了一种基于拟共形映射理论的新方法。所得理论的影响在多个应用中得以体现,包括著名单叶函数类Sigma中的系数估计、与算子理论的联系、容量计算以及基于矩的重建算法。

英文摘要:

We establish the strong asymptotics for Bergman orthogonal polynomials defined over Jordan domains with corners. This complements an investigation started in 1923 by T. Carleman, who derived the strong asymptotics for domains bounded by analytic curves, and carried over by P.K. Suetin in the 1960's, who established them for domains with smooth boundaries. In order to do so, we use a new approach based on tools from quasiconformal mapping theory. The impact of the resulting theory is demonstrated in a number of applications, varying from coefficient estimates in the well-known class Sigma of univalent functions and a connection with operator theory, to the computation of capacities and a reconstruction algorithm from moments.
