Real-variable characterizations of Musielak–Orlicz Hardy spaces on spaces of homogeneous type

open access: yes, 2020
Let (X , d, μ) be a space of homogeneous type in the sense of Coifman and Weiss. In this article, the authors establish a complete real-variable theory of Musielak–Orlicz Hardy spaces on (X , d, μ).

On the inconsistency of the Bohm-Gadella theory with quantum mechanics [PDF]

open access: yes, 2006
The Bohm-Gadella theory, sometimes referred to as the Time Asymmetric Quantum Theory of Scattering and Decay, is based on the Hardy axiom. The Hardy axiom asserts that the solutions of the Lippmann-Schwinger equation are functionals over spaces of Hardy ...

On the boundedness of subsequences of Vilenkin-Fejér means on the martingale Hardy spaces [PDF]

open access: yes, 2020
In this paper we characterize subsequences of Fejer means with respect to Vilenkin systems, which are bounded from the Hardy space $H_{p}$ to the Lebesgue space $L_{p},$ for all ...

A new approach to norm inequalities on weighted and variable Hardy spaces [PDF]

open access: yesAnnales Academiae Scientiarum Fennicae: Mathematica, 2019
We give new proofs of Hardy space estimates for fractional and singular integral operators on weighted and variable exponent Hardy spaces. Our proofs consist of several interlocking ideas: finite atomic decompositions in terms of $L^\infty$ atoms, vector-

A Complete Real-Variable Theory of Hardy Spaces on Spaces of Homogeneous Type [PDF]

open access: yesJournal of Fourier Analysis and Applications, 2018
Let $$(X,d,\mu )$$(X,d,μ) be a space of homogeneous type, with the upper dimension $$\omega $$ω, in the sense of Coifman and Weiss. Assume that $$\eta $$η is the smoothness index of the wavelets on X constructed by Auscher and Hytönen.

Boundedness for Commutators of Rough p-Adic Hardy Operator on p-Adic Central Morrey Spaces

open access: yesJournal of Function Spaces, 2021
In the present article we obtain the boundedness for commutators of rough p-adic Hardy operator on p-adic central Morrey spaces. Furthermore, we also acquire the boundedness of rough p-adic Hardy operator on Lebesgue spaces.

Real-variable characterizations of Orlicz-slice Hardy spaces [PDF]

open access: yesAnalysis and Applications, 2018
In this paper, the authors first introduce a class of Orlicz-slice spaces which generalize the slice spaces recently studied by Auscher et al. Based on these Orlicz-slice spaces, the authors then introduce a new kind of Hardy-type spaces, the Orlicz ...

Hardy-type spaces and Hardy-type inequalities

open access: yesAIMS Mathematics
In the present paper, we defined and then studied Hardy spaces related to spherical mean operators. We proved Hardy-type inequalities, then we showed refined Sobolev-type inequalities between homogeneous Riesz-type spaces, homogeneous Besov-type spaces ...

Variable exponent Hardy spaces associated with discrete Laplacians on graphs

open access: yes, 2017
In this paper we develop the theory of variable exponent Hardy spaces associated with discrete Laplacians on infinite graphs. Our Hardy spaces are defined by square integrals, atomic and molecular decompositions.

Hardy spaces of generalized analytic functions and composition operators

open access: yesConcrete Operators, 2018
We present some recent results on Hardy spaces of generalized analytic functions on D specifying their link with the analytic Hardy spaces. Their definition can be extended to more general domains Ω . We discuss the way to extend such definitions to more
