Abstract: |
The following singular Kirchhoff-type equations with critical Hardy-Sobolev exponent are considered, ⎛-(a+b∫Ω|▽u|2dx) △u=(u5-2s)/(|x|s)+λu-γ,x∈Ω, ⎨u > 0,x ∈Ω, ⎝u=0,x ∈∂Ω, where Ω⊂R3 is an open bounded domain with smooth boundary ∂Ω,0 ∈Ω,a,b ≥ 0 and a+b > 0,λ > 0,0 < γ < 1,0 ≤ s < 1. By the variational methods, the existence of positive local minimal solutions is obtained, which complements the result of[1]. |
