We prove a multiplicity result for the Yamabe problem on the manifold (S, g~), where g~is a perturbation of the standard metric g 0 of S n . Solutions are found by variational methods via an abstract perturbation result.

β¦ Synopsis
Given any constant C > 0, we show that there exists Ξ΅ 0 > 0 such that for any Ξ΅ < Ξ΅ 0 , the problem
has no solution u Ξ΅ , whose energy, A Ξ΅ |βu Ξ΅ | 2 , is less than C, where A Ξ΅ is a ringshaped open set in R n and n 4. ο 2002 Γditions scientifiques et mΓ©dicales Elsevier SAS

In this paper we consider the following nonlinear elliptic problem (P):u = u p , u > 0 in , u = 0 on β , where is a bounded and smooth domain in R n , n 4, p + 1 = 2n/(n -2) is the critical Sobolev exponent. We prove a version of Morse lemmas at infinity for this problem. As application of these lem
