矩阵正交多项式的微分性质

Differential properties of matrix orthogonal polynomials

M. J. Cantero, L. Moral, L. Velazquez

摘要:

本文发展了半经典矩阵正交多项式的一般理论。我们利用分布方程$D(u A) = u B,$定义半经典线性泛函,其中$A$和$B$是矩阵多项式.利用相应的(左)矩阵正交多项式序列给出了这些半经典泛函的几个刻画。它们涉及导数的拟正交性、结构关系和二阶微分微分方程。最后,我们用一些非平凡的例子来说明前面的结果。

英文摘要:

In this paper a general theory of semi-classical matrix orthogonal polynomials is developed. We define the semi-classical linear functionals by means of a distributional equation $D(u A) = u B,$ where $A$ and $B$ are matrix polynomials. Several characterizations for these semi-classical functionals are given in terms of the corresponding (left) matrix orthogonal polynomials sequence. They involve a quasi-orthogonality property for their derivatives, a structure relation and a second order differo-differential equation. Finally we illustrate the preceding results with some non-trivial examples.
