Sharp exponential integrability of conjugate functions

David Norrbo, Jani Virtanen

We prove that if a real-valued function $f \in L^{1}$ on the complex unit circle has a gap of width at least $π$ in its essential range, then $exp (f)$ is not integrable, w…

The Boundedness Problem for Generalized Hilbert Operators on Hardy Spaces

David Norrbo, José Ángel Peláez, Fanglei Wu

Let $g$ be analytic in the unit disc and consider the generalized Hilbert operator $H_{g} (f) (z) = \int_{0}^{1} f (t) g^{'} (t z) d t .$ The boundedness of $H_{g}$ on $H^{p}$ is…

Generalized Hilbert matrix operators acting on Bergman spaces

Carlo Bellavita, Vassilis Daskalogiannis, Santeri Miihkinen +3

In this article we study the generalized Hilbert matrix operator $Γ_{μ}$ acting on the Bergman spaces $A^{p}$ of the unit disc for $1 \leq p < \infty$ . In particular, we characterize the…
