Abstract

A two-parameter family of polynomials is introduced by a recursion formula. The polynomials are orthogonal on the unit circle with respect to the weight ω_α,β(θ)=(1-z)^α(1+z) ^β2, α,β-12, z=e^iθ. Explicit representation, norm estimates, shift identities, and explicit connection to Jacobi polynomials on the real interval [-1,1] is presented.
