On some nonlinear elliptic problems for p –Laplacian in

Nodea-nonlinear Differential Equations and Applications, 2008

In this paper, we consider a nonlinear elliptic problem involving the p-Laplacian with perturbation terms in the whole mathbbRN\mathbb {R}^NmathbbRN . Via variational arguments, we obtain existence and regularity of nontrivial solutions.

On semilinear elliptic equations with borderline Hardy potentials

Journal d'Analyse Mathématique, 2014

In this paper we study the asymptotic behavior of solutions to an elliptic equation near the singularity of an inverse square potential with a coefficient related to the best constant for the Hardy inequality. Due to the presence of a borderline Hardy potential, a proper variational setting has to be introduced in order to provide a weak formulation of the equation. An Almgrentype monotonicity formula is used to determine the exact asymptotic behavior of solutions. Date: September 21, 2012. 2010 Mathematics Subject Classification. 35J75, 35B40, 35B45. Key words and phrases. Hardy's inequality, singular elliptic operators, asymptotic behavior of solutions. V.

Existence and qualitative properties of solutions to a quasilinear elliptic equation involving the Hardy–Leray potential

Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2014

In this work we deal with the existence and qualitative properties of the solutions to a supercritical problem involving the −∆p(•) operator and the Hardy-Leray potential. Assuming 0 ∈ Ω, we study the regularizing effect due to the addition of a first order nonlinear term, which provides the existence of solutions with a breaking of resonance. Once we have proved the existence of a solution, we study the qualitative properties of the solutions such as regularity, monotonicity and symmetry.

Existence of radial solutions for quasilinear elliptic equations with singular nonlinearities

Advanced Nonlinear Studies

We prove the existence of radial solutions of the quasilinear elliptic equation div(A(|Du|)Du) + f (u) = 0 in R n , n > 1, where f is either negative or positive for small u > 0, possibly singular at u = 0, and growths subcritically for large u. Our proofs use only elementary arguments based on a variational identity. No differentiability assumptions are made on f .

The Existence of Multiple Solutions to Quasilinear Elliptic Equations

Bulletin of the London Mathematical Society, 2005

Using Morse theory and the truncation technique, a proof is given of the existence of at least three nontrivial solutions for a class of p-Laplacian equations. When p = 2, the existence of four nontrivial solutions is also considered.
