Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
A new method for constructing Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space is presented. In earlier research, we only dealt with scalar-valued weight functions.

Asymptotics of orthogonal polynomials inside the unit circle and Szegö-Padé approximants [PDF]

open access: yes, 2001
11 pages, no figures.-- MSC2000 codes: 42C05, 41A21.MR#: MR1858277 (2002h:42043)Zbl#: Zbl 1009.42016We study the asymptotic behavior of orthogonal polynomials inside the unit circle for a subclass of measures that satisfy Szegö's condition.

Skew-orthogonal Laguerre polynomials for chiral real asymmetric random matrices [PDF]

open access: yes, 2010
We apply the method of skew-orthogonal polynomials (SOP) in the complex plane to asymmetric random matrices with real elements, belonging to two different classes. Explicit integral representations valid for arbitrary weight functions are derived for the

Fourier coefficients for Laguerre–Sobolev type orthogonal polynomials [PDF]

open access: yesArab Journal of Mathematical Sciences, 2023
Purpose – In this paper, the authors take the first step in the study of constructive methods by using Sobolev polynomials. Design/methodology/approach – To do that, the authors use the connection formulas between Sobolev polynomials and classical ...

Orthogonal polynomials and Möbius transformations [PDF]

open access: yesComputational and Applied Mathematics, 2021
Given an orthogonal polynomial sequence on the real line, another sequence of polynomials can be found by composing these polynomials with a general Möbius transformation. In this work, we study the properties of such Möbius-transformed polynomials. We show that they satisfy an orthogonality relation in given curve of the complex plane with respect to ...

Large degree asymptotics of orthogonal polynomials with respect to an oscillatory weight on a bounded interval [PDF]

open access: yes, 2014
We consider polynomials p^w_n(x) that are orthogonal with respect to the oscillatory weight w(x)=exp(iwx) on [?1,1], where w>0 is a real parameter. A first analysis of p^?_n(x) for large values of w was carried out in connection with complex Gaussian ...

Szegő polynomials: some relations to L-orthogonal and orthogonal polynomials

open access: yesJournal of Computational and Applied Mathematics, 2003
The authors consider the Szegö polynomials \(S_n(z)\) with real reflection coefficients and obtain some relations to certain self-inverse orthogonal \(L\)-polynomials defined on the unit circle and corresponding symmetric orthogonal polynomials on a real line. The polynomials obtained by rotating the coefficients in the recursive relations satisfied by

Recurrence coefficients for discrete orthonormal polynomials and the Painlevé equations [PDF]

open access: yes, 2013
We investigate semi-classical generalizations of the Charlier and Meixner polynomials, which are discrete orthogonal polynomials that satisfy three-term recurrence relations.

RECURRENCE RELATIONS FOR SOBOLEV ORTHOGONAL POLYNOMIALS

open access: yesПроблемы анализа, 2020
We consider recurrence relations for the polynomials orthonormal with respect to the Sobolev-type inner product and generated by classical orthogonal polynomials, namely: Jacobi polynomials, Legendre polynomials, Chebyshev polynomials of the first and ...
