Orthogonal polynomials for the oscillatory-Gegenbauer weight
Milovanović Gradimir V., Cvetković Aleksandar S., Marjanović Zvezdan M.
This is a continuation of our previous investigations on polynomials orthogonal with respect to the linear functional L : P→C, where L = ∫1 -1 p(x) dμ(x), dμ(x) = (1-x²)λ-1/2 exp(iζx) dx, and P is a linear space of all algebraic polynomials. Here, we prove an extension of our previous existence theorem for rational λ ∈ (-1/2,0], give some hypothesis on three-term recurrence coefficients, and derive some differential relations for our orthogonal polynomials, including the second order differential equation.
