โœฆ Synopsis


Conditions on the geometric structure of a complete Riemannian manifold are given to solve the prescribed scalar curvature problem. In some cases, the conformal metric obtained is complete. A minimizing sequence is constructed which converges strongly to a solution. ยฉ Academic des ScienceslElsevier, Paris Probleme de courbure scalaire prescrite sur les varietes riemanniennes completes

On presente dans cette Note des resultats concernant I'existence de solutions du probleme de courbure scalaire prescrite sur les varietes riemanniennes completes. II est resolu sous certaines hypotheses geometriques. Dans certains cas la nouvelle metrique obtenue est complete.

La difficulte nouvelle par rapport au cas compact est la possible concentration al'infini d'une suite minimisante qui converge vers la solution. C'est pour eviter un tel phenomene que les conditions geometriques sont utilisees. Une autre difficulte est d'obtenir une metrique complete. Ceci est realise dans certains cas qui seront mentionnes.

Voici les deux theorernes obtenus : THEOREME 1. -II existe une solutionpositive de l'equation (*) sous les hypotheses: 1. en un point P 014 10 fonction f atteint son maximum. on suppose que Weyl(P) =f; 0 et D.gf(P) = Ll;f(P) = 0, de plus n > 6 .. Note presentee par Thierry A UBIN.

Let (M, g) be a compact Riemannian manifold of dimension n ~2. First, we study the existence of positive solutions for generalized scalar curvature type equations; these equations are nonlinear, of critical Sobolev growth, and involve the p-Laplacian. Then, we study similar type of equations, but in
