Abstract

We consider the following critical weakly coupled elliptic system \begincases -Δu_i = μ_i |u_i|^{2^*-2}u_i + ∑_{j ≠ i} β_ij |u_j|^{(2^*)/(2)} |u_i|^{(2^*-4)/(2)} u_i amp; in Ω_ε u_i gt;0 amp; in Ω_ε u_i = 0 amp; on ∂ Ω_ε,\endcases i =1,…,m, in a domain Ω_ε ⊂ ℝ^N, N=3,4, with small shrinking holes as the parameter ε → 0. We prove the existence of positive solutions of two different types: either each density concentrates around a different hole, or we have groups of components such that all the components within a single group concentrate around the same point, and different groups concentrate around different points.
