Beurling and Model subspaces invariant under a universal operator

Ben Hur Eidt, S. Waleed Noor, Waleed Noor

We classify the Beurling and model subspaces of the Hardy space $H^2(\mathbb{D})$ that are invariant under the composition operators $C_{{\varphi }_a}$, where ${\varphi }_a(z)=az+1-a$ and $0<a<1$. Th…
