Abstract: In this paper we study a new concept of quasi-orthogonality on the unit circle, depending of the structure of the orthogonal polynomials on the unit circle, and we consider its relation with the semi-classical linear forms.
Keywords: Orthogonal polynomials; quasi-orthogonal polynomials; semi-classical linear forms.
