Improved $\ell^p$-Boundedness for Integral $k$-Spherical Maximal Functions

open access: yesDiscrete Analysis, 2018
Improved $\ell^p$-Boundedness for Integral $k$-Spherical Maximal Functions, Discrete Analysis 2018:10, 18pp. An important role in harmonic analysis is played by the notion of a _maximal function_ (which is actually a non-linear operator on a space of ...

On Some Properties of Hardy- Littlewood Maximal Operators on Hardy Spaces Built upon BFS

open access: yes, 2019
Operator theory studied by very mathematicians, we refer to [1,2,3,4,5]. Compactification of weighted Hardy operator in variable exponent Lebesgue spaces has been proof by [6].

Abstract Weighted Morrey Spaces and Applications

open access: yesAxioms
We introduce the abstract weighted Morrey spaces Mp,uκ(X,M,μ), where μ is a general measure; investigate the properties of their predual spaces; and prove the boundedness of the Hardy–Littlewood maximal operator.

Weighted Lorentz Norm Inequalities for the One-Sided Hardy-Littlewood Maximal Functions and for the Maximal Ergodic Operator

open access: yes, 1994
In this paper we characterize weighted Lorentz norm inequalities for the one sided Hardy-Littlewood maximal functionSimilar questions are discussed for the maximal operator associated to an invertible measure preserving transformation of a measure space.
