摘要: It is shown that there exists Λ>0 such that, for every λ∈(0,Λ), the semilinear elliptic system:-Δu=λu|u|q-1+u|u| p-1-v in Ω,- Δv=δuv in Ω, u=v=0 on ∂Ω, where Ω∈RN(N≥2) is a bounded domain with smooth boundary and 0<q<1<p,has a minimal positive solution (uλ,vλ). Moreover: uλ and vλ are strictly increasing with respect to λ.
