On the Hilbert matrix operator: a brief survey
Carlo Bellavita, Vassilis Daskalogiannis, Georgios Stylogiannis
This article aims to explore the most recent developments in the study of the Hilbert matrix, acting as an operator on spaces of analytic functions and sequence spaces. We present…
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 acting on the Bergman spaces of the unit disc for . In particular, we characterize the…
A variant of Hilbert's inequality and the norm of the Hilbert Matrix on
Vassilis Daskalogiannis, Petros Galanopoulos, Michael Papadimitrakis
We prove the nontrivial variant \[ \sum\limits_{m,n=1}^{\infty}\Big(\frac{n}{m}\Big)^{\frac{1}{q}-\frac{1}{p}}\frac{a_mb_n}{m+n-1}\leq\fracπ{\sin\fracπ{p}} \Big( \sum\limits_{m=1}^…
Generalized Hilbert operators arising from Hausdorff matrices
Carlo Bellavita, Nikolaos Chalmoukis, Vassilis Daskalogiannis +1
For a finite, positive, Borel measure on we consider an infinite matrix , related to the classical Hausdorff matrix defined by the same measure , in the same al…
Holomorphic semigroups and Sarason's characterization of vanishing mean oscillation
Nikolaos Chalmoukis, Vassilis Daskalogiannis
It is a classical theorem of Sarason that an analytic function of bounded mean oscillation (), is of vanishing mean oscillation if and only if its rotations converge in norm…
Semigroups of composition operators and Integral operators in BMOA-type spaces
Vassilis Daskalogiannis, Petros Galanopoulos
The aim of this article is to study semigroups of composition operators on the BMOA-type spaces , and on their "little oh" analogues . The spaces were intr…
