The factorization of the weighted Hardy space in terms of multilinear Calderón-Zygmund operators

open access: yes, 2023
summary:We give a constructive proof of the factorization theorem for the weighted Hardy space in terms of multilinear Calderón-Zygmund operators. The result is also new even in the linear setting.

Riesz's Functions in Weighted Hardy and Bergman Spaces [PDF]

open access: yesCanadian Journal of Mathematics, 1996
AbstractLet μ be a finite positive Borel measure on the closed unit disc . For each a in , put where ƒ ranges over all analytic polynomials with f(a) = 1. This upper semicontinuous function S(a) is called a Riesz's function and studied in detail. Moreover several applications are given to weighted Bergman and Hardy spaces.

Weighted Hardy Spaces on the Unit Disk [PDF]

open access: yesComplex Analysis and Operator Theory, 2014
In this paper we mainly discuss three things. First, there is no canonical norm on the space $H^p_u(\mathbb{D})$. Second, we improve the weak-$*$ convergence of the measures $μ_{u,r}$. Third, the dilations $f_t$ of the function $f\in H^p_u(\mathbb{D})$ converge to $f$ in $H^p_u$-norm and hence the polynomials are dense in $H^p_u(\mathbb{D})$.

On weighted generalized composition operators on weighted hardy spaces

open access: yesFilomat, 2020
The present paper introduces the class of weighted generalized composition operators of higher order defined on the weighted Hardy spaces. The study of bounded operators belonging to this class is undertaken and an attempt is made to describe their structural and spectral properties.

Hardy Operators and Commutators on Weighted Herz Spaces

open access: yesAnalysis in Theory and Applications, 2023
Summary: Let \(P\) be the classical Hardy operator on \((0, \infty)\) and \(Q\) be the adjoint operator. In this paper, we get the boundedness for \(P\), \(Q\) and the commutators of \(P\) and \(Q\) with \(CMO\) functions on the weighted Herz spaces.

A sufficient condition for the boundedness of operator-weighted martingale transforms and Hilbert transform [PDF]

open access: yes, 2007
Let W be an operator weight taking values almost everywhere in the bounded positive invertible linear operators on a separable Hilbert space H. We show that if W and its inverse W−1 both satisfy a matrix reverse Holder property introduced in [2], then ...

Weighted Composition Operators on Hardy Spaces

open access: yesJournal of Mathematical Analysis and Applications, 2001
This paper studies operators of the form \(f\mapsto (f\circ\varphi)\psi\) acting on Hardy spaces \(H^p\) of the unit disk \(D\), where \(\psi\) is analytic in \(D\) and \(\varphi\) is an analytic self-map of \(D\). Problems studied include the boundedness, compactness, weak compactness, and complete continuity of such operators.
