Cyclic Blaschke products for composition operators

Eva A. Gallardo-Gutiérrez and Pamela Gorkin

Full-text: Open access


In this work, cyclic Blaschke products for composition operators induced by disc automorphisms are studied. In particular, we obtain interpolating Blaschke products that are cyclic for nonelliptic automorphisms and we obtain a new characterization of Blaschke products that are not finite products of interpolating Blaschke products.
