On the Krall‐type polynomials [PDF]

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 5, Page 359-369, 2004., 2004
Using a general and simple algebraic approach, some results on Krall‐type orthogonal polynomials and some of their extensions are obtained.

A semicircle law and decorrelation phenomena for iterated Kolmogorov loops

open access: yesJournal of the London Mathematical Society, Volume 103, Issue 2, Page 558-586, March 2021., 2021
Abstract We consider a standard one‐dimensional Brownian motion on the time interval [0,1] conditioned to have vanishing iterated time integrals up to order N. We show that the resulting processes can be expressed explicitly in terms of shifted Legendre polynomials and the original Brownian motion, and we use these representations to prove that the ...

Some results on a generalized ω‐Jacobi transform

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 63, Page 3379-3387, 2004., 2004
We introduce a generalized ω‐Jacobi transform and obtain images of certain functions under this transform. Moreover, we define a new probability density function (pdf) involving this new generalized ω‐Jacobi function. Some basic functions associated with the pdf, such as characteristic function, moments and distribution function, are evaluated.

Various results in relation with the hypergeometric equations and the hypergeometric functions in the complex plane

open access: yes, 2020
The main purpose of this investigation is to specify an extensive relation between the hypergeometric functions and the hypergeometric equations in the complex plane and then to point various implications of our main result, conclusion and also ...

The second‐order self‐associated orthogonal sequences

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 2, Page 137-167, 2004., 2004
The aim of this work is to describe the orthogonal polynomials sequences which are identical to their second associated sequence. The resulting polynomials are semiclassical of class s ≤ 3. The characteristic elements of the structure relation and of the second‐order differential equation are given explicitly.

The Hermite polynomials and the Bessel functions from a general point of view

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 57, Page 3633-3642, 2003., 2003
We introduce new families of Hermite polynomials and of Bessel functions from a point of view involving the use of nonexponential generating functions. We study their relevant recurrence relations and show that they satisfy differential‐difference equations which are isospectral to those of the ordinary case.

Generalized Spectral Projections for the Weinstein Laplacian and Applications

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, we investigate the generalized spectral projections associated with the Weinstein Laplacian −ΔdW,α. We first derive an explicit integral formula for these projections and prove that they are intrinsically linked to the spectral density of −ΔdW,α, which endows them with a natural spectral interpretation.

On a generalized Jacobi transform

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 4, Page 371-385, 2002., 2002
In this paper, we study a generalized Jacobi transform and obtain images of certain functions under this transform. Furthermore, we define a Jacobi random variable and derive its moments, distribution function, and characteristic function.
