AI-generated Abstract

This paper investigates the existence of solutions for the Dirichlet problem associated with the p-Laplacian operator in unbounded domains. It focuses on a specific setting where the nonlinearity exhibits subcritical growth. Using variational methods and critical point theory, the study establishes conditions under which nontrivial solutions exist, thereby contributing to the understanding of non-linear partial differential equations in mathematical analysis.

On a Dirichlet problem involving p-Laplacian

International Mathematical Forum, 2007

In this paper, the existence of at least three weak solutions for Dirichlet problem Δ p u + λf (x, u) = 0 in Ω, u = 0 on ∂Ω, where Δ p u =div(|∇u| p−2 ∇u) is the p-Laplacian operator, Ω ⊂ R N (N ≥ 1) is non-empty bounded open set with smooth boundary ∂Ω , p > N, λ > 0 and f : Ω × R → R is a L 1-Caratheodory function, is established. The approach is based on variational methods and critical points.

EXISTENCE AND MULTIPLICITY OF SOLUTIONS FOR A DIRICHLET PROBLEM INVOLVING PERTURBED p(x)-LAPLACIAN OPERATOR

In this article we study the existence of solutions for the Dirichlet problem − div(||u| p(x)−2 u) + V (x)|u| q(x)−2 u = f (x, u) in Ω, u = 0 on ∂Ω, where Ω is a smooth bounded domain in R N , V is a given function in a generalized Lebesgue space L s(x) (Ω) and f (x, u) is a Carathéodory function which satisfies some growth condition. Using variational arguments based on " Fountain theorem " and " Dual Fountain theorem " , we shall prove under appropriate conditions on the above nonhomogeneous quasilinear problem the existence of two sequences of weak solutions for this problem.

Existence and nonexistence results for quasilinear elliptic equations involving the p-laplacian

The paper deals with the study of a quasilinear elliptic equation involving the p-laplacian with a Hardy-type singular potential and a critical nonlinearity. Existence and nonexistence results are first proved for the equation with a concave singular term. Then we study the critical case relate to Hardy inequality, providing a description of the behavior of radial solutions of the limiting problem and obtaining existence and multiplicity results for perturbed problems through variational and topological arguments.
