Beyond the continuous case, the theory has been "developed" into broader frameworks available in academic texts like The Classical Orthogonal Polynomials by B.G.S. Doman: The Classical Orthogonal Polynomials

is the Kronecker delta. These polynomials are foundational in mathematical physics, numerical analysis, and approximation theory. 1. Identify the core families The Classical Orthogonal Polynomials
