AI中文摘要:
在给定所有零点均为正实数且零点在$(0,\infty)$上具有渐近零点分布的条件下,我们给出了多项式序列系数的渐近行为。我们展示了系数的极限如何与渐近零点分布的Stieltjes变换相关联,并将其与自由概率中的$S$-变换联系起来。我们通过涉及正交多项式和多重正交多项式的一些例子加以说明。
英文摘要:
The asymptotic behavior of the coefficients of a sequence of polynomials is given under the conditions that all the zeros are real and positive and the zeros have an asymptotic zero distribution on $(0,\infty)$. We show how the limit for the coefficients is related to the Stieltjes transform of the asymptotic zero distribution and make a connection with the $S$-transform in free probability. We illustrate with some examples involving orthogonal and multiple orthogonal polynomials.
