Spectral analysis for the exceptional Xm-Jacobi equation
We provide the mathematical foundation for the $X_m$-Jacobi spectral theory. Namely, we present a self-adjoint operator associated to the differential expression with the exceptional $X_m$-Jacobi orthogonal polynomials as eigenfunctions.

An upper bound on Jacobi polynomials
Let ${\bf P}_k^{( , )} (x)$ be an orthonormal Jacobi polynomial of degree $k.$ We will establish the following inequality \begin{equation*} \max_{x \in [ _{-1}, _1]}\sqrt{(x- _{-1})( _1-x)} (1-x)^ (1+x)^ ({\bf P}_{k}^{( , )} (x))^2 < \frac{3 \sqrt{5}}{5}, \end{equation*} where $ _{-1}

On Saigo Fractional $q$-Calculus of a General Class of $q$-Polynomials [PDF]
In this paper, we derive Saigo fractional $q$-integrals of the general class of $q$-polynomials and demonstrate their application by investigating $q$-Konhouser biorthogonal polynomial, $q$-Jacobi polynomials and basic analogue of the Kamp$\acute{e}$ de

Shifted Jacobi polynomials and Delannoy numbers [PDF]
We express a weighted generalization of the Delannoy numbers in terms of shifted Jacobi polynomials. A specialization of our formulas extends a relation between the central Delannoy numbers and Legendre polynomials, observed over 50 years ago, to all Delannoy numbers and certain Jacobi polynomials.
arxiv
This paper is concerned with representing sums of the finite products of Chebyshev polynomials of the second kind and of Fibonacci polynomials in terms of several classical orthogonal polynomials.

Generating functions for the Jacobi polynomial [PDF]
Two theorems are proved with the aid of operator and series iteration methods. Special cases appear to give new and known generating functions for the Jacobi polynomial.

Riemann–Liouville Operator in Weighted Lp Spaces via the Jacobi Series Expansion
In this paper, we use the orthogonal system of the Jacobi polynomials as a tool to study the Riemann−Liouville fractional integral and derivative operators on a compact of the real axis.

The Stenger conjectures and the A-stability of collocation Runge-Kutta methods
Stenger conjectures are claims about the location of the eigenvalues of matrices whose elements are certain integrals involving basic Lagrange interpolating polynomials supported on the zeros of orthogonal polynomials. In this paper, we show the validity
