Nonlinear elliptic systems with variable exponents and measure data

Moroccan Journal of Pure and Applied Analysis, 2015

In this paper we prove existence results for distributional solutions of nonlinear elliptic systems with a measure data. The functional setting involves Lebesgue-Sobolev spaces as well as weak Lebesgue (Marcinkiewicz) spaces with variable exponents W01,p(·)(Ω) and Mp(·)(Ω) respectively.

Existence of renormalized solutions for nonlinear elliptic problems in weighted variable-exponent space with L^1-data

Gulf Journal of Mathematics, 2018

In this paper we study the existence of a renormalized solution for the nonlinear p(x)-elliptic problem in the Weighted-Variable-Exponent Soblev spaces, of the form: −div(a(x, u, ∇u)) + H(x, u, ∇u) = f in Ω, where the right-hand side f belong to L 1 (Ω) and H(x, s, ξ) is the nonlinear term satisfying some growth condition, but no sign condition on s.

Existence and Regularity of Solution for Strongly Nonlinear p(x)-Elliptic Equation with Measure Data

Journal of Partial Differential Equations

The first part of this paper is devoted to study the existence of solution for nonlinear p(x) elliptic problem A(u) = µ in Ω, u = 0 on ∂Ω, with a right-hand side measure, where Ω is a bounded open set of R N , N 2 and A(u) = −div(a(x,u,∇u)) is a Leray-Lions operator defined from W 1,p(x) 0 (Ω) in to its dual W −1,p ′ (x) (Ω). However the second part concerns the existence solution, of the following setting nonlinear elliptic problems A(u)+ g(x,u,∇u) = µ in Ω, u = 0 on ∂Ω. We will give some regularity results for these solutions.

The regularity of weak solutions to nonlinear scalar field elliptic equations containing p&q-Laplacians

Annales- Academiae Scientiarum Fennicae Mathematica

In this paper, we consider the regularity of weak solutions u ∈ W 1,p (R N ) ∩ W 1,q (R N ) of the elliptic partial differential equation where 1 < q < p < N . We prove that these solutions are locally in C 1,α and decay exponentially at infinity. Furthermore, we prove the regularity for the solutions u where N ≥ 3, 1 < q < p < N , and f (x, u) is of critical or subcritical growth about u. As an application, we can show that the solution we got in [8] has the same regularity.

Entropy and renormalized solutions for nonlinear elliptic problem involving variable exponent and measure data

Acta Mathematica Sinica, English Series, 2014

We give an existence result of entropy and renormalized solutions for strongly nonlinear elliptic equations in the framework of Sobolev spaces with variable exponents of the type: −div (a(x, u, ∇u) + φ(u)) + g(x, u, ∇u) = μ, where the right-hand side belongs to L 1 (Ω) + W −1,p (x) (Ω), −div(a(x, u, ∇u)) is a Leray-Lions operator defined from W −1,p (x) (Ω) into its dual and φ ∈ C 0 (R, R N). The function g(x, u, ∇u) is a non linear lower order term with natural growth with respect to |∇u| satisfying the sign condition, that is, g(x, u, ∇u)u ≥ 0.

Infinitely many solutions for elliptic problems with variable exponent and nonlinear boundary conditions

Nonlinear Differential Equations and Applications NoDEA, 2011

We analyze a class of quasilinear elliptic problems involving a p(•)-Laplace-type operator on a bounded domain Ω ⊂ R N , N ≥ 2, and we deal with nonlinear conditions on the boundary. Working on the variable exponent Lebesgue-Sobolev spaces, we follow the steps described by the "fountain theorem" and we establish the existence of a sequence of weak solutions.
