Abstract: | We discussed the Dirichlet problem of semilinear elliptic equation (P
β,ε):β
2Δu=u
p
+εu,u>0, in Ω;u=0, on ∂Ω, where Ω⊂R
N
(N≥4) is smooth and bounded domain,
,β,ε>0. We have proved that there exist positiveε
0 andε
1, such that when 0⩽ε⩽ε
0,β>√ε
1, (P
β,ε) has a single-peaked solutionu
β,ε; furthermore, |∇u
β0|2⇀0 in the sense of measure as ε→0 and β→0.
