Mention très honorableOn a compact Riemannian manifold of dimension larger than 3,we consider a particular elliptic non linear equation : the Sobolev Poincaré equation. Firstly, we describe the asymptotic behaviour of sequences of solutions of this equation thanks to a fine analysis of the concentration phenomenon. Then we get results of multiplicity of solutions for this equation by introducing isometry invariances. Our method gives also multiplicity results for more classical critical equations like the Yamabe or the Nirenberg equation, and also for overcritical equations. Our work is strongly related to the description of the best constants in functionnal inequalities of Sobolev.Sur une variété riemanienne compacte de dimension supérieur...
