On discrete q-ultraspherical polynomials and their duals
We show that a confluent case of the big q-Jacobi polynomials P_n(x;a,b,c;q), which corresponds to a=b=-c, leads to a discrete orthogonality relation for imaginary values of the parameter a (outside of its commonly known domain 01, this family represents yet another q-extension of these classical polynomials, different from the continuous q ...

Monotonicity Properties of the Zeros of Ultraspherical Polynomials
Let \(x_{n,k}^{(\lambda)}\), \(k=1,2,\dots,[n,2]\), denote the \(k\)-th positive zero in increasing order of the ultraspherical polynomial \(P_n^{(\lambda)}(x)\). The authors prove that the function \([\lambda+(2n^2+1)/(4n+2)]^{1/2}x_{n,k}^{(\lambda)}\) is increasing for \(\lambda>-1/2\). This proves the Ismail-Letessier-Askey conjecture [\textit{M. E.

Estimates for polynomials orthogonal with respect to some Gegenbauer–Sobolev type inner product
In this paper we obtain some estimates in for orthogonal polynomials with respect to an inner product of Sobolev-type where Finally, the asymptotic behavior of such polynomials in is analyzed.

Zeros of quasi-orthogonal ultraspherical polynomials
It is known that the zeros of orthogonal polynomials of successive degrees interlace on the interval of orthogonality. This paper investigates ultraspherical polynomials \(C_n^{(\lambda)}\) orthogonal with respect to the weight function \((1-x^2)^{\lambda-1/2}\) on the interval \([-1,1]\).
