Rhaly operators on weighted Hardy spaces and factorable matrices

Carlo Bellavita, Eugenio Dellepiane, Georgios Stylogiannis

In this paper, we study properties of Rhaly operators acting on weighted Hardy spaces $H^{2} (ω)$ . This problem is intimately related to the study of factorable matrices on $ℓ^{2}$ .…

The spectral analysis of the difference quotient operator on model spaces

Carlo Bellavita, Eugenio Alberto Dellepiane, Javad Mashreghi

We conduct a spectral analysis of the difference quotient operator $Q_{ζ}^{u}$ , associated with a boundary point $ζ \in \partial D$ , on the model space $K_{u}$ . We describe the o…

Embedding model and de Branges-Rovnyak spaces in Dirichlet spaces

Carlo Bellavita, Eugenio Alberto Dellepiane

In this paper we study embeddings between de Branges-Rovnyak spaces $H (b)$ and harmonically weighted Dirichlet spaces $D (μ)$ in terms of the boundary spectrum of $b$ and…
