We will look at embeddings and composition operators on coinvariant
subspaces of the Hardy space, so called model spaces.
In particular we investigate the case in which the defining inner
function is one-component, developing an extension process to
reduce to the study of an equivalent embedding operator on a
Hardy-Smirnov space of a different domain. From there
we deduce criteria for embeddings and composition operators to be
p-Schatten, obtaining characterizations that
are in the spirit of previous work of Baranov and Luecking, Zhu.
Based on joint work with Alexandru Aleman, Yura Lyubarskii, and Eugenia
Malinnikova.
