    International audienceWe consider the Dirichlet Problem for equations involving the Laplacian in the case "beyond the first eigenvalue" and with right hand side with critical growth

    International audienceThis paper is devoted to the existence and Lipschitz regularity of viscosity solutions for a class of very degenerate fully nonlinear operators, on the model of the pseudo p-Laplacian. We also prove a strong maximum principle.Dans cet artcile on montre des résultats d'existence et de régularité pour les solutions d'une classe d'équations complètement non linéaires très dégénérées, sur le modèle de l'équation du pseudo pp Laplacien

    Eigenvalue and Dirichlet problem for fully-nonlinear operators in non smooth domains

    No full text
    20 pages no pictureInternational audienceWe study the maximum principle, the existence of eigenvalue and the existence of solution for the Dirichlet problem relative to operators which are fully-nonlinear, elliptic but presenting some singularity or degeneracy which are similar to those of the p-Laplacian, we consider the equations in bounded domains which only satisfy the exterior cone condition

    One-dimensional symmetry for solutions of Allen Cahn fully nonlinear equations.

    16 pages, no pictureInternational audienceThis article presents some qualitative results for solutions of the fully nonlinear elliptic equation F(∇u,D2u) + f(u) = 0 in IRN. Precisely under some additional assumptions on f, if −1 ≤ u ≤ 1 and limx1→±∞ u(x1,x′) = ±1 uniformly with respect to x′, then the solution depends only on x1

    EIGENVALUE, MAXIMUM PRINCIPLE AND REGULARITY FOR FULLY NON LINEAR HOMOGENEOUS OPERATORS

    No full text
    32pages no pictureInternational audienceThe main scope of this article is to define the concept of principal eigenvalue for fully non linear second order operators in bounded domains that are elliptic, homogenous with lower order terms. In particular we prove maximum and comparison principle, H ̈older and Lipschitz regularity. This leads to the existence of a first eigenvalue and eigenfunction and to the existence of solutions of Dirichlet problems within this class of operators
