Multiple little q-Jacobi polynomials [PDF]

open access: yes, 2004
We introduce two kinds of multiple little q-Jacobi polynomials by imposing orthogonality conditions with respect to r discrete little q-Jacobi measures on the exponential lattice q^k (k=0,1,2,3,...), where 0 < q < 1.

Matrix-Valued Little q-Jacobi Polynomials [PDF]

open access: yes, 2014
Matrix-valued analogues of the little q-Jacobi polynomials are introduced and studied. For the 2x2-matrix-valued little q-Jacobi polynomials explicit expressions for the orthogonality relations, Rodrigues formula, three-term recurrence relation and their

Jacobi Polynomials on the Bernstein Ellipse [PDF]

open access: yesJournal of Scientific Computing, 2017
In this paper, we are concerned with Jacobi polynomials $P_n^{( , )}(x)$ on the Bernstein ellipse with motivation mainly coming from recent studies of convergence rate of spectral interpolation. An explicit representation of $P_n^{( , )}(x)$ is derived in the variable of parametrization. This formula further allows us to show that the maximum value

Differentiation by integration with Jacobi polynomials

open access: yesJournal of Computational and Applied Mathematics, 2011
In this paper, the numerical differentiation by integration method based on Jacobi polynomials originally introduced by Mboup, Fliess and Join is revisited in the central case where the used integration window is centered. Such method based on Jacobi polynomials was introduced through an algebraic approach and extends the numerical differentiation by ...

The structure relation for Askey-Wilson polynomials [PDF]

open access: yes, 2006
An explicit structure relation for Askey-Wilson polynomials is given. This involves a divided q-difference operator which is skew symmetric with respect to the Askey-Wilson inner product and which sends polynomials of degree n to polynomials of degree n ...

On the Behaviour of Zeros of Jacobi Polynomials

open access: yesJournal of Approximation Theory, 2002
AbstractDenote by xn,k(α,β) and xn,k(λ)=xn,k(λ−1/2,λ−1/2) the zeros, in decreasing order, of the Jacobi polynomial P(α,β)n(x) and of the ultraspherical (Gegenbauer) polynomial Cλn(x), respectively. The monotonicity of xn,k(α,β) as functions of α and β, α,β>−1, is investigated. Necessary conditions such that the zeros of P(a,b)n(x) are smaller (greater)

On linearization coefficients of Jacobi polynomials [PDF]

open access: yesApplied Mathematics Letters, 2010
AbstractThis article deals with the problem of finding closed analytical formulae for generalized linearization coefficients for Jacobi polynomials. By considering some special cases, we obtain a reduction formula using for this purpose symbolic computation, in particular Zeilberger’s and Petkovsek’s algorithms.

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.
