Trace ideal criteria for embeddings and composition operators on model spaces

A. Aleman, Yu. Lyubarskii, E. Malinnikova +1

Let $K_{\theta }$ be a model space generated by an inner function $\theta$. We study the Schatten class membership of embeddings $I:K_{\theta }\to L^2(\mu )$, $\mu$ a positive measure, and of composition…
