✦ Synopsis
We define a "renormalized" Morse index, and prove a Bahri-Lions type result for critical points of E(u, v) = Ω {∇u • ∇v -H (x, u, v)} dx; i.e., we establish an a priori bound for critical points with bounded Morse index. © 2000 Éditions scientifiques et médicales Elsevier SAS RÉSUMÉ. -Nous définissons un indice de Morse généralisé pour les points critiques de la fonction
Le but principal de ce travail est la démonstration d'une estimation de type Bahri-Lions [2] pour les points critiques. Nous montrons pour chaque entier m ∈ N que l'ensemble des points critiques dont l'indice renormalisé µ satisfait µ m est borné dans L ∞ (Ω) × L ∞ (Ω).

In this paper, we develop a Sturm Liouville type theory for the nodal sets and Morse indices of solutions of super-linear elliptic PDEs with Dirichlet boundary condition. It shows that there are some relationships between analytic properties (e.g., L p -norm, vanishing order of the nodal point, and
## Abstract In the investigation of the spectral theory of non‐selfadjoint elliptic boundary value problems involving an indefinite weight function, there arises the problem of obtaining __L^p^__ a priori estimates for solutions about points of discontinuity of the weight function. Here we deal wit
