Consider a system {φn} of polynomials orthonormal on the unit circle with respect to the measure dµ with μ′ > 0 almost everywhere. Then
$$\mathop {\lim }\limits_{n \to \infty } \int_{ - \pi }^\pi {\left| {\left| {\phi _n \left( {e^{i\theta } } \right)} \right|\sqrt {\mu '\left( \theta \right)} - 1} \right|^2 } d\theta = 0.$$

This result enables one to extend many results of Szegö's theory to the case μ′ > 0.
