The Hardy space H1 on non-homogeneous metric spaces [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2010
Let (, d, μ) be a metric measure space and satisfy the so-called upper doubling condition and the geometrical doubling condition. We introduce the atomic Hardy space H1(μ) and prove that its dual space is the known space RBMO(μ) in this context.

Geometric Hardy and Hardy–Sobolev inequalities on Heisenberg groups

open access: yesBulletin of Mathematical Sciences, 2020
In this paper, we present geometric Hardy inequalities for the sub-Laplacian in half-spaces of stratified groups. As a consequence, we obtain the following geometric Hardy inequality in a half-space of the Heisenberg group with a sharp constant: ∫ℍ ...

Complete Continuity of Composition-Differentiation Operators on the Hardy Space H1

open access: yesJournal of Function Spaces, 2023
We study composition-differentiation operators on the Hardy space H1 on the unit disk. We prove that if φ is an analytic self-map of the unit disk such that the composition-differentiation operator induced by φ is bounded on the Hardy space H1, then it ...

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Molecular Characterizations and Dualities of Variable Exponent Hardy Spaces Associated with Operators

open access: yes, 2015
Let $L$ be a linear operator on $L^2(\mathbb R^n)$ generating an analytic semigroup $\{e^{-tL}\}_{t\ge0}$ with kernels having pointwise upper bounds and $p(\cdot):\ \mathbb R^n\to(0,1]$ be a variable exponent function satisfying the globally log-H\"older

HARDY SPACE OF LOMMEL FUNCTIONS

open access: yes, 2015
. In this work we present some geometric properties (like star-likeness and convexity of order α and also close-to-convexity of order(1+α)/2) for normalized of Lommel functions of the first kind.

New abstract Hardy spaces

open access: yesJournal of Functional Analysis, 2008
The aim of this paper is to propose an abstract construction of spaces which keep the main properties of the (already known) Hardy spaces H^1. We construct spaces through an atomic (or molecular) decomposition. We prove some results about continuity from these spaces into L^1 and some results about interpolation between these spaces and the Lebesgue ...

Numerical Range on Weighted Hardy Spaces as Semi Inner Product Spaces

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
The semi-inner product, in the sense of Lumer, on weighted Hardy space which generate the norm is unique. Also we will discuss some properties of the numerical range of bounded linear operators on weighted Hardy spaces.

Weighted composition operators on Hardy–Smirnov spaces

open access: yesConcrete Operators, 2022
Operators of type f → ψf ◦ φ acting on function spaces are called weighted composition operators. If the weight function ψ is the constant function 1, then they are called composition operators.
