Riesz and Wolff potentials and elliptic equations in variable exponent weak Lebesgue spaces [PDF]

open access: yes, 2015
We prove optimal integrability results for solutions of the p(x)-Laplace equation in the scale of (weak) Lebesgue spaces. To obtain this, we show that variable exponent Riesz and Wolff potentials map L1 to variable exponent weak Lebesgue ...

A mass transportation approach for Sobolev inequalities in variable exponent spaces [PDF]

open access: yes, 2015
In this paper we provide a proof of the Sobolev-Poincar\'e inequality for variable exponent spaces by means of mass transportation methods. The importance of this approach is that the method is exible enough to deal with different inequalities.

Uniform Convexity in Variable Exponent Sobolev Spaces

open access: yesSymmetry, 2023
We prove the modular convexity of the mixed norm Lp(ℓ2) on the Sobolev space W1,p(Ω) in a domain Ω⊂Rn under the sole assumption that the exponent p(x) is bounded away from 1, i.e., we include the case supx∈Ωp(x)=∞. In particular, the mixed Sobolev norm is uniformly convex if 1<infx∈Ωp(x)≤supx∈Ωp(x)<∞ and W01,p(Ω) is uniformly convex.

Approximation by Zygmund means in variable exponent Lebesque spaces [PDF]

open access: yesMathematica Moravica, 2019
In the present work we investigate the approximation of the functions by the Zygmund means in variable exponent Lebesgue spaces. Here the estimate which is obtained depends on sequence of the best approximation in Lebesgue spaces with variable exponent ...

Characterization of Riesz and Bessel potentials on variable Lebesgue spaces

open access: yesJournal of Function Spaces and Applications, 2006
Riesz and Bessel potential spaces are studied within the framework of the Lebesgue spaces with variable exponent. It is shown that the spaces of these potentials can be characterized in terms of convergence of hypersingular integrals, if one assumes that

Existence and Uniqueness of Renormalized Solution to Nonlinear Anisotropic Elliptic Problems with Variable Exponent and L1-Data

open access: yesInternational Journal of Differential Equations, 2023
Nonlinear partial differential equations are considered as an essential tool for describing the behavior of many natural phenomena. The modeling of some phenomena requires to work in Sobolev spaces with constant exponent.

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.

Local Characterizations of Besov and Triebel-Lizorkin Spaces with Variable Exponent

open access: yesJournal of Function Spaces, 2014
We introduce new Besov and Triebel-Lizorkin spaces with variable integrable exponent, which are different from those introduced by the second author early.
