Stieltjes多项式的交错和渐近性质

Interlacing and asymptotic properties of Stieltjes polynomials

A. Bourget, T. McMillen

摘要:

多项式的解决方案,以广义拉梅方程,\textit{Stieltjes polynomials},和相关的\textit{Van Vleck polynomials}已研究自1830年以来,开始与拉梅在他的研究拉普拉斯方程的椭圆,并在不断扩大各种应用。本文给出了Stieltjes多项式的零点分布,并提出了两个新的交错定理。我们安排的Stieltjes多项式根据其Van Vleck零和显示,首先,连续Stieltjes多项式的相同程度的零交错,其次,连续度Stieltjes多项式的零交错。我们利用这些结果推导出Stieltjes和Van Vleck多项式的新的渐近性质。我们还表明,没有序列的Stieltjes多项式正交。

英文摘要:

Polynomial solutions to the generalized Lamé equation, the \textit{Stieltjes polynomials}, and the associated \textit{Van Vleck polynomials} have been studied since the 1830's, beginning with Lamé in his studies of the Laplace equation on an ellipsoid, and in an ever widening variety of applications since. In this paper we show how the zeros of Stieltjes polynomials are distributed and present two new interlacing theorems. We arrange the Stieltjes polynomials according to their Van Vleck zeros and show, firstly, that the zeros of successive Stieltjes polynomials of the same degree interlace, and secondly, that the zeros of Stieltjes polynomials of successive degrees interlace. We use these results to deduce new asymptotic properties of Stieltjes and Van Vleck polynomials. We also show that no sequence of Stieltjes polynomials is orthogonal.
