Estimates for p-adic multilinear Hardy–Littlewood operators on variable Morrey–Herz spaces

Open Mathematics
We obtain some necessary and sufficient conditions for the boundedness of the p-adic multilinear Hardy–Littlewood operators Hφ,n,m ${\mathcal{H}}_{\varphi ,n,m}$ on the p-adic Morrey–Herz spaces ∏i=1mMK̇ℓ,qi(⋅),ωiαi(⋅),λiQpn $\prod _{i=1}^{m}{M \dot {K}}

Weighted Variable Exponent Sobolev spaces on metric measure spaces

Moroccan Journal of Pure and Applied Analysis, 2018
In this article we define the weighted variable exponent-Sobolev spaces on arbitrary metric spaces, with finite diameter and equipped with finite, positive Borel regular outer measure.

An Efficient Algorithm for Reconstruction Images Corrupted by Some Multiplicative Noises

Moroccan Journal of Pure and Applied Analysis, 2019
In this paper, we propose a novel hybrid model for restoration of images corrupted by multiplicative noise. Using a MAP estimator, we can derive a functional whose minimizer corresponds to the denoised image we want to recover.

Non-ideal sampling in shift-invariant spaces associated with quadratic-phase Fourier transforms

Alexandria Engineering Journal, 2023
Non-ideal sampling has nourished as one of the most attractive alternatives to classical sampling, which relies on shift-invariant spaces. The present study focuses on investigating the non-ideal sampling in shift-invariant spaces associated with the ...

Standing waves for Choquard equation with noncritical rotation

Advances in Nonlinear Analysis
We investigate the existence and stability of standing waves with prescribed mass c>0c\gt 0 for Choquard equation with noncritical rotation in Bose-Einstein condensation. Then, we consider the mass collapse behavior of standing waves, the ratio of energy

Zygmund inequality of the conjugate function on Morrey-Zygmund spaces

Demonstratio Mathematica, 2019
We generalize the Zygmund inequality for the conjugate function to the Morrey type spaces defined on the unit circle T. We obtain this extended Zygmund inequality by introducing the Morrey-Zygmund space on T.

The Lusin Theorem and Horizontal Graphs in the Heisenberg Group

Analysis and Geometry in Metric Spaces, 2013
In this paper we prove that every collection of measurable functions fα , |α| = m, coincides a.e. withmth order derivatives of a function g ∈ Cm−1 whose derivatives of order m − 1 may have any modulus of continuity weaker than that of a Lipschitz ...

Grand Triebel-Lizorkin-Morrey spaces

Demonstratio Mathematica
This article studies the Triebel-Lizorkin-type spaces built on grand Morrey spaces on Euclidean spaces. We establish a number of characterizations on the grand Triebel-Lizorkin-Morrey spaces such as the Peetre maximal function characterizations, the ...

Pointwise Multipliers on Weak Morrey Spaces

Analysis and Geometry in Metric Spaces, 2020
We consider generalized weak Morrey spaces with variable growth condition on spaces of homogeneous type and characterize the pointwise multipliers from a generalized weak Morrey space to another one.
