Abstract

A one to one correspondence is established between the nondegenerate critical points of in and single peaked solutions of the problem

where is a bounded domain, , , and .

In particular, we establish the uniqueness of the least energy solution when attains its maximum in at only one nondegenerate critical point in .

Résumé

On établit une correspondance biunivoque entre les points critiques non-dégénérés de en , et les solutions à un seul pic du problème

est un domaine borné, , , et .

En particulier, nous démontrons l’unicité de la solution de moindre énergie lorsque achève son maximum dans en un seul point critique non-dégénéré.
