Abstract
In this paper, we give an exact behavior on the boundary and at infinity of the unique solution to the following singular boundary value problem −Δu=a(x)g(u),x∈Ω,u>0,in Ω,u|∂Ω=0 and lim|x|→∞u(x)=0. Here ΩΩ is an exterior domain in Rn(n≥3) with compact C2C2-boundary, g∈C1((0,∞),(0,∞))g∈C1((0,∞),(0,∞)) is nonincreasing on (0,∞)(0,∞) with limt→0g′(t)∫0tdsg(s)=−Cg≤0 and the function aa is in Clocα(Ω), 0<α<10<α<1 satisfying 0
