On Christoffel Type Functions for Lm Extremal Polynomials, II
Throughout this paper let m be an even integer and M :=[0, 2, 4, ..., m&2]. Let + be a nondecreasing function on R with infinitely many points of increase such that all moments of d+ are finite. We call d+ a measure. For N # N let PN denote the set of polynomials of degree at most N and P*N the subset of polynomials in PN having real zeros only. We agree P0 *=P0 . Put P*N(x) :=[P # P*N : P(x)=1...
متن کاملUltraspherical Type Generating Functions for Orthogonal Polynomials
We characterize, under some technical assumptions and up to a conjecture, probability distributions of finite all order moments with ultraspherical type generating functions for orthogonal polynomials. Our method is based on differential equations and the obtained measures are particular Beta distributions. We actually recover the free Meixner family of probability distributions so that our met...
متن کاملUltraspherical Type Generating Functions for Orthogonal Polynomials
We characterize the probability distributions of finite all order moments having generating functions for orthogonal polynomials of ultraspherical type. 1. Motivation: Meixner families There is a one to one correspondance between probability distributions on the real line and polynomials of a one variable satisfying a three-terms recurrence relation subject to some positive conditions ([9]). Th...

متن کاملOn the Christoffel–darboux Formula for Generalized Matrix Orthogonal Polynomials
We obtain an extension of the Christoffel–Darboux formula for matrix orthogonal polynomials with a generalized Hankel symmetry, including the Adler-van Moerbeke generalized orthogonal polynomials.
