A proof of conjectures of Esterle and Ransford on negative powers of contractions

William Verreault

Building on work of Ransford, we prove that whenever $E$ is a closed subset of the unit circle of Lebesgue measure zero, there exists a positive sequence $u_{n} \to \infty$ such that i…

The Cesàro operator on local Dirichlet spaces

Eugenio Dellepiane, Javad Mashreghi, Mostafa Nasri +1

The family of Cesàro operators $σ_{n}^{α}$ , $n \geq 0$ and $α \in [0, 1]$ , consists of finite rank operators on Banach spaces of analytic functions on the open unit disc. In this work, w…

Nonlinear expansions in reproducing kernel Hilbert spaces

Javad Mashreghi, William Verreault

We introduce an expansion scheme in reproducing kernel Hilbert spaces, which as a special case covers the celebrated Blaschke unwinding series expansion for analytic functions. The…
