Abstract : For $q$ close to ${N+2\over N-2}$, $N\geq 3$, positive solutions of $\Delta u + \lambda u + u^q = 0$ in a bounded, smooth domain $\Omega$ in $\R^N$, with zero Dirichlet boundary conditions, are considered. For $N=3$, existence in the super- and sub-critical regimes is stated and a duality between both cases is established. Under additional symmetry conditions, multiplicity corresponding to towers of bubbles holds in the super-critical regime. A sketch of the proofs is provided. The case $N\geq 4$ is also treated.
