Abstract:In this contribution we analyze the generating functions for polynomials orthogonal with respect to a symmetric linear functional u, i.e., a linear application in the linear space of polynomials with complex coefficients such that u(x 2n+1 ) = 0. In some cases we can deduce explicitly the expression for the generating functionwhere {Pn}n is the sequence of orthogonal polynomials with respect to u.
“…Semiclassical symmetric linear functionals of order at most two are the natural framework of our study. They have been analyzed by many authors (see [33][34][35][36][37], among others). On the other hand, the so-called symmetrization process for linear functionals (see [3]) will play a central role in this contribution.…”
In this paper, we study a classification of symmetric ( 1 , 1 ) -coherent pairs by using a symmetrization process. In particular, the positive-definite case is carefully described.
