Orthogonality of Jacobi polynomials with general parameters

A. B. J. Kuijlaars, A. Martinez-Finkelshtein, R. Orive

In this paper we study the orthogonality conditions satisfied by Jacobi polynomials $P_n^{(\alpha ,\beta )}$ when the parameters $\alpha$ and $\beta$ are not necessarily $>-1$. We establish orthogonal…
