Two limit transitions involving multivariable BC type Askey-Wilson polynomials

Jasper Stokman (1997)

Banach Center Publications

Similarity:

In the first part (without proofs) an orthogonality measure with partly discrete and partly continuous support will be introduced for the five parameter family of multivariable BC type Askey-Wilson polynomials. In the second part, the limit transitions from BC type Askey-Wilson polynomials to BC type big and little q-Jacobi polynomials will be described in detail.

Linearization of the product of orthogonal polynomials of a discrete variable

Saïd Belmehdi, Stanisław Lewanowicz, André Ronveaux (1997)

Applicationes Mathematicae

Similarity:

Let P k be any sequence of classical orthogonal polynomials of a discrete variable. We give explicitly a recurrence relation (in k) for the coefficients in P i P j = k c ( i , j , k ) P k , in terms of the coefficients σ and τ of the Pearson equation satisfied by the weight function ϱ, and the coefficients of the three-term recurrence relation and of two structure relations obeyed by P k .
