简介：在这份报纸，我们考虑下列非线性的椭圆形的问题：2u=|u|8n−4u+|u|q−1u，在里面u=u=0在∂ 上；一跳并且在Rn的光滑的领域，n∈{5,6,7}Rn，n∈{5,6,7}， ；是一个参数和q ∈]4/(n−4)，(12−n)/(n−4)[q ∈]4/(n−4)，(12−n)/(n−4)[。我们学习在二个点附近专注的答案。我们证明集中速度是一样的顺序和从对方的集中点的距离并且从边界被围住。为=()光滑的ringshaped开的集合，我们证实在二点专注的积极答案的存在指。最后，我们显示出那为>0，足够大，这个问题作为Ljusternik-Schnirelman范畴有至少许多积极答案。
