The Hardy–Littlewood Maximal Operator on Discrete Morrey Spaces [PDF]

open access: yesMediterranean Journal of Mathematics, 2019
We discuss the Hardy-Littlewood maximal operator on discrete Morrey spaces of arbitrary dimension. In particular, we obtain its boundedness on the discrete Morrey spaces using a discrete version of the Fefferman-Stein inequality. As a corollary, we also obtain the boundedness of some Riesz potentials on discrete Morrey spaces.

Sharp Inequalities for the Hardy–Littlewood Maximal Operator on Finite Directed Graphs

open access: yesMathematics, 2021
In this paper, we introduce and study the Hardy–Littlewood maximal operator MG→ on a finite directed graph G→. We obtain some optimal constants for the ℓp norm of MG→ by introducing two classes of directed graphs.

Best constants for the Hardy–Littlewood maximal operator on finite graphs

open access: yesJournal of Mathematical Analysis and Applications, 2016
We study the behavior of averages for functions defined on finite graphs $G$, in terms of the Hardy-Littlewood maximal operator $M_G$. We explore the relationship between the geometry of a graph and its maximal operator and prove that $M_G$ completely determines $G$ (even though embedding properties for the graphs do not imply pointwise inequalities ...

A pointwise estimate for pseudo-differential operators

open access: yesBulletin of Mathematical Sciences, 2023
Let [Formula: see text] be a pseudo-differential operator defined by the symbol [Formula: see text] with [Formula: see text] [Formula: see text]. It is shown that if [Formula: see text], then the operator satisfies the following pointwise estimate: (Tau)♯

Norm inequalities for the minimal and maximal operator, and differentiation of the integral [PDF]

open access: yes, 1997
We study the weighted norm inequalities for the minimal operator, a new operator analogous to the Hardy-Littlewood maximal operator which arose in the study of reverse Hölder inequalities.

On the boundedness of the fractional maximal operator on global Orlicz-Morrey spaces

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
The article deals with the global Orlia-Morrey spaces GMΦ,ϕ,θ(Rn). We find sufficient conditions on pairs of functions (ϕ, η) and (Φ, Ψ), which ensure the boundedness of the fractional maximal operator Mα from GMΦ,ϕ,θ(Rn) in GMΨ,η,θ(Rn).

Density of Analytic Polynomials in Abstract Hardy Spaces [PDF]

open access: yes, 2017
Let $X$ be a separable Banach function space on the unit circle $\mathbb{T}$ and $H[X]$ be the abstract Hardy space built upon $X$. We show that the set of analytic polynomials is dense in $H[X]$ if the Hardy-Littlewood maximal operator is bounded on the
