A form (linear functional) u is called regular if there exists a sequence of polynomials {P n } n 0 , deg P n = n, which is orthogonal with respect to u. Such a form is said to be semi-classical, if there exist two polynomials Φ and Ψ such that (Φu) + Ψ u = 0. Now, this form is said to be of second
