Abstract

The lassical Sarason transform is the canonical isomorphism of the model space H2/gqH2 (θ is an inner function generated by a single point mass) onto the standard L2 space. In the paper the image of the space of smooth functions H 2 1 ={f: f′ ε H2} under this transform is described in explicit terms. Pointwise estimates of the model operator in H 2 1 /θH 2 1 are obtained. Bibliography: 5 titles.
