经典正交多项式零点附近的扰动

Perturbations around the zeros of classical orthogonal polynomials

Ryu Sasaki

摘要:

从经典正交多项式的不定常Schroedinger方程的N次解出发,导出了描述多项式N个零点附近扰动的线性矩阵方程.该矩阵具有显著的丢番图性质。它的特征值与零点无关。对应的特征向量提供了较低次数(0,1,.,N-1)多项式的次数。这些结果对所有经典的正交多项式都是普遍有效的,包括超几何正交多项式的Askey格式及其q-模拟.

英文摘要:

Starting from degree N solutions of a time dependent Schroedinger-like equation for classical orthogonal polynomials, a linear matrix equation describing perturbations around the N zeros of the polynomial is derived. The matrix has remarkable Diophantine properties. Its eigenvalues are independent of the zeros. The corresponding eigenvectors provide the representations of the lower degree (0,1,...,N-1) polynomials in terms of the zeros of the degree N polynomial. The results are valid universally for all the classical orthogonal polynomials, including the Askey scheme of hypergeometric orthogonal polynomials and its q-analogues.
