Abstract (VO)
Résumé

In this Note we consider a class of noncoercive nonlinear problems whose prototype is

- △_{p} u + b (x) {| \nabla u |}^{λ} = μ in Ω, u = 0 on \partial Ω,

where

Ω

is a bounded open subset of

ℝ^{N}

(N⩾2), △_p is the so called p-Laplace operator (1<p<N) or a variant of it, μ is a Radon measure with bounded variation on

Ω

or a function in

L^{1} (Ω)

, λ⩾0 and b belongs to the Lorentz space

L^{N, 1} (Ω)

or to the Lebesgue space

L^{\infty} (Ω)

. We prove existence and uniqueness of renormalized solutions.

Dans cette Note nous considérons une classe de problèmes non linéaires et non coercifs dont le prototype est

- △_{p} u + b (x) {| \nabla u |}^{λ} = μ dans Ω, u = 0 sur \partial Ω,

où

Ω

est un ouvert borné de

ℝ^{N}

(N⩾2), △_p est le p-Laplacien (1<p<N) ou une variante de cet opérateur, μ est une mesure de Radon bornée ou une function de

L^{1} (Ω)

, λ⩾0 et b appartient à l'espace de Lorentz

L^{N, 1} (Ω)

ou à l'espace de Lebesgue

L^{\infty} (Ω)

. Nous démontrons l'existence et l'unicité de solutions renormalisées de ce problème.
