Turán inequalities for symmetric orthogonal polynomials.
Two limit transitions involving multivariable BC type Askey-Wilson polynomials
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.
