Multi-bubble solutions for slightly super-critical elliptic problems in domains with symmetries

The aim of this paper is to show the existence of solutions with an arbitrarily large number of bubbles for the slightly super-critical elliptic problem -Deltau = u((N+2)/(N-2)+epsilon) in Omega, subject to the conditions that u > 0 in Omega, and u = 0 on partial derivativeOmega, where epsilon > 0 is a small parameter and Omega subset of R(N) is a bounded domain with certain symmetries, for instance an annulus or a torus in R(3).
