Sur une équation elliptique non linéaire avec l’exposant critique de Sobolev. (On a nonlinear elliptic equation involving the critical Sobolev exponent). (French) Zbl 0601.35040

We prove the existence of a positive solution u of the equation \(\Delta u+u^ 5=0\), \(u=0\) on \(\partial \Omega\) where \(\Omega\) is a non contractible open bounded set in \({\mathbb{R}}^ 3\).
