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 ...

On the Connection Coefficients of the Chebyshev-Boubaker Polynomials

open access: yesThe Scientific World Journal, 2013
The Chebyshev-Boubaker polynomials are the orthogonal polynomials whose coefficient arrays are defined by ordinary Riordan arrays. Examples include the Chebyshev polynomials of the second kind and the Boubaker polynomials.

Orthogonal Homogeneous Polynomials

open access: yesAdvances in Applied Mathematics, 1999
These are stringent results on real homogeneous polynomials in several real variables: if the polynomials form a normalized biorthogonal system (with respect to a certain inner product, which is defined using partial derivatives of one of the components), then an addition theorem holds, and conversely: the addition property is sufficient for ...

On Certain Properties and Applications of the Perturbed Meixner–Pollaczek Weight

open access: yesMathematics, 2021
This paper deals with monic orthogonal polynomials orthogonal with a perturbation of classical Meixner–Pollaczek measure. These polynomials, called Perturbed Meixner–Pollaczek polynomials, are described by their weight function emanating from an ...

Planar orthogonal polynomials as Type II multiple orthogonal polynomials [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2019
Abstract We show that the planar orthogonal polynomials with l logarithmic singularities in the potential are the multiple orthogonal polynomials (Hermite–Padé polynomials) of Type II with l measures. We also find the ratio between the

Vibration of beams using novel boundary characteristic orthogonal polynomials satisfying all boundary conditions

open access: yesAdvances in Mechanical Engineering, 2015
Boundary characteristic orthogonal polynomials proposed by the author in 1985 have been used in the Rayleigh Ritz method extensively in order to obtain natural frequencies of vibrating plates with different boundary conditions.

Generating new classes of orthogonal polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Given a sequence of monic orthogonal polynomials (MOPS), {Pn}, with respect to a quasi-definite linear functional u, we find necessary and sufficient conditions on the parameters an and bn for the sequence Pn(x)+anPn−1(x)+bnPn−2(x),   n≥1P0(x)=1,P−1(x ...
