## Abstract

We consider the boundary value problem Δ*u*+⋎*x*⋎^{2α}*u*^{p}=0, α>0, in the unit ball*B* with homogeneous Dirichlet boundary condition and*p* a large exponent. We find a condition which ensures the existence of a positive solution*u*_{p} concentrating outside the origin at*k* symmetric points as*p* goes to +∞. The same techniques lead also to a more general result on general domains. In particular, we find that concentration at the origin is always possible, provided α⊄*IN*.
