Abstract: This paper deals with a problem proposed by H.Brezis on the existence of positive solutions to the equation $\triangle{u}+u^{(n+2)/(n-2)}+f(x,u)=0$ under the Neumann boundary condition $D_{\gamma}=u^{n/(n-2)}$ where $f(x,u)$ is a lower order perturbation of $u^{(n+2)/(n-2)}$ at infinity.

Keywords:

Neumann problem, Semilinear elliptic equation, Positive solution.
