Abstract

The aims of this paper are to extend the concept of classical orthogonal polynomials sequence by introducing the concept of semiclassical quasi-orthogonal polynomials sequence applying an analogous method that we considered in (q-Classical orthogonal polynomial: A general difference calculus approach (with F Marcellán) Acta Appl. Math. 2009] to present a unify study of SQOPS by using the differential (difference and q-difference) calculus, and to obtain a new characterization theorem for these quasi-orthogonal polynomials sequences. Some semiclassical quasi-orthogonal polynomials are presented in detail.
