Weighted Grand Herz‐Type Spaces and Its Applications

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, we introduce the weighted grand Herz spaces and weighted grand Herz‐type Hardy spaces. The decompositional characterizations of these spaces are established. As its applications, the boundedness of some sublinear operators are established.

Littlewood–Paley Characterization for Musielak–Orlicz–Hardy Spaces Associated with Self‐Adjoint Operators

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
Let (X, d, μ) be a metric measure space endowed with a metric d and a non‐negative Borel doubling measure μ. Let L be a non‐negative self‐adjoint operator on L2(X). Assume that the (heat) kernel associated to the semigroup e−tL satisfies a Gaussian upper bound.

A Study on Some New Generalizations of Reversed Dynamic Inequalities of Hilbert‐Type via Supermultiplicative Functions

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this article, we establish some new generalizations of reversed dynamic inequalities of Hilbert‐type via supermultiplicative functions by applying reverse Hölder inequalities with Specht’s ratio on time scales. We will generalize the inequalities by using a supermultiplicative function which the identity map represents a special case of it. Also, we

Commutators of Pseudodifferential Operators on Weighted Hardy Spaces

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we establish an endpoint estimate for the commutator, [b, T], of a class of pseudodifferential operators T with symbols in Hörmander class Sρ,δmRn. In particular, there exists a nontrivial subspace of BMORn such that, when b belongs to this subspace, the commutators [b, T] is bounded from Hω1Rn into Lω1Rn, which we extend the well‐known ...

Scalar and vector Muckenhoupt weights [PDF]

open access: yesIndiana University Mathematics Journal, 2007
We inspect the relationship between the A p,q condition for families of norms on vector valued functions and the Ap condition for scalar weights. In particular, we will show if we are considering a norm-valued function ρ (·) such that, uniformly in all nonzero vectors X, ρ (·) (x) p ∈ Ap and ρ* (·) (x) q ∈ Aq, then the following hold: If p = q = 2,

Almost everywhere convergence of Bochner–Riesz means on Heisenberg‐type groups

open access: yesJournal of the London Mathematical Society, Volume 103, Issue 3, Page 1066-1119, April 2021., 2021
Abstract We prove an almost everywhere convergence result for Bochner–Riesz means of Lp functions on Heisenberg‐type groups, yielding the existence of a p>2 for which convergence holds for means of arbitrarily small order. The proof hinges on a reduction of weighted L2 estimates for the maximal Bochner–Riesz operator to corresponding estimates for the ...

Local Boundedness and Harnack Inequality for Solutions of Linear Nonuniformly Elliptic Equations

open access: yesCommunications on Pure and Applied Mathematics, Volume 74, Issue 3, Page 453-477, March 2021., 2021
Abstract We study local regularity properties for solutions of linear, nonuniformly elliptic equations. Assuming certain integrability conditions on the coefficient field, we prove local boundedness and Harnack inequality. The assumed integrability assumptions are essentially sharp and improve upon classical results by Trudinger.

Global gradient estimates for Dirichlet problems of elliptic operators with a BMO antisymmetric part

open access: yesAdvances in Nonlinear Analysis, 2022
Let n≥2n\ge 2 and Ω⊂Rn\Omega \subset {{\mathbb{R}}}^{n} be a bounded nontangentially accessible domain. In this article, the authors investigate (weighted) global gradient estimates for Dirichlet boundary value problems of second-order elliptic equations

Sobolev spaces with non-Muckenhoupt weights, fractional elliptic operators, and applications [PDF]

open access: yes, 2018
We propose a new variational model in weighted Sobolev spaces with non-standard weights and applications to image processing. We show that these weights are, in general, not of Muckenhoupt type and therefore the classical analysis tools may not apply ...
