Abstract

We find necessary and sufficient conditions for an orthogonal polynomial system to be compatible with another orthogonal polynomial system. As applications, we find new characterizations of semi-classical and classical orthogonal polynomials.

Keywords: orthogonal polynomials, compatibility, semi-classical and classical orthogonal polynomials, inverse problem
