A Through-the-Wall Imaging Approach Based on a TSVD/Variable-Exponent Lebesgue-Space Method

open access: yesRemote Sensing, 2021
A hybrid inversion scheme for through-the-wall imaging is proposed in this paper. The approach is based on a linearized model of the inverse-scattering problem, employing the Green’s function developed for a layered background.

Algebras of singular integral operators with piecewise continuous coefficients on weighted Nakano spaces [PDF]

open access: yes, 2006
We find Fredholm criteria and a formula for the index of an arbitrary operator in the Banach algebra of singular integral operators with piecewise continuous coefficients on Nakano spaces (generalized Lebesgue spaces with variable exponent) with ...

Asymptotic Behavior of Solutions to a Nonlinear Swelling Soil System with Time Delay and Variable Exponents

open access: yesMathematical and Computational Applications, 2023
In this research work, we investigate the asymptotic behavior of a nonlinear swelling (also called expansive) soil system with a time delay and nonlinear damping of variable exponents.

Boundedness for commutators of fractional integrals on Herz-Morrey spaces with variable exponent

open access: yes, 2013
In this paper, some boundedness for commutators of fractional integrals are obtained on Herz-Morrey spaces with variable exponent applying some properties of varible exponent and $\BMO$ function.Comment: In 2013, it is accepted by Kyoto Journal of ...

A trace inequality for generalized potentials in Lebesgue spaces with variable exponent

open access: yesJournal of Function Spaces and Applications, 2004
A trace inequality for the generalized Riesz potentials Iα(x) is established in spaces Lp(x) defined on spaces of homogeneous type. The results are new even in the case of Euclidean spaces.

Generalized Concentration-Compactness Principles for Variable Exponent Lebesgue Spaces with Asymptotic Analysis of Low Energy Extremals

open access: yesMathematics, 2020

Embeddings between grand, small and variable Lebesgue spaces

open access: yes, 2017
We give conditions on the exponent function $p(\cdot)$ that imply the existence of embeddings between grand, small and variable Lebesgue spaces. We construct examples to show that our results are close to optimal.
