|Title:||Multidimensional boundary layers for a singularly perturbed Neumann problem|
|Abstract:||We continue the study of , proving concentration phenomena for the equation -epsilon(2) Deltau + u = u(p) in a smooth bounded domain Omega subset of or equal to R-n and with Neumann boundary conditions. The exponent p is greater than or equal to 1, and the parameter epsilon is converging to zero. For a suitable sequence epsilon(j) --> 0, we prove the existence of positive solutions u(j) concentrating at the whole boundary of Omega or at some of its components.|
