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…
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…
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…
