与扰动链序列对应的实直线上的正交多项式

Orthogonal polynomials on the real line corresponding to a perturbed chain sequence

Kiran Kumar Behera, A. Swaminathan

摘要:

近年来,链序列及其扰动在刻画实直线上和单位圆上的正交多项式中起着重要的作用。本文研究了正交多项式的链序列的一个特殊扰动,它的真正交区间是$[0,\infty)$的一个子集,从而得到了与核多项式有关的一个重要结论.这种扰动被证明是有关的对称措施的转换。最后给出了使用广义拉盖尔多项式的例子。

英文摘要:

In recent years, chain sequences and their perturbations have played a significant role in characterising the orthogonal polynomials both on the real line as well as on the unit circle. In this note, a particular disturbance of the chain sequence related to orthogonal polynomials having their true interval of orthogonality as a subset of $[0,\infty)$ is studied leading to an important consequence related to the kernel polynomials. Such perturbations are shown to be related to transformations of symmetric measures. An illustration using the generalized Laguerre polynomials is also provided.
