Abstract :
The purpose of the present contribution is to investigate the effects of finite modifications of Verblunsky coefficients on Szegő recurrences. More precisely, we study the structural relations and the corresponding C -functions of the orthogonal polynomials with respect to these modifications from the initial ones.
