考虑半线性椭圆方程组 {△u+λf(u,v)=0,x∈Ω △u+λg(u,v)=0,x∈Ω u(x)+v(x)=0,x∈δΩ 其中λ〉0,Ω是有界光滑区域.f,g是定义在R2:=[0,∞)×[0,∞)上的实值函数,讨论在满足什么条件下此半线性椭圆方程组存在唯一的正解.
In this paper, we consider the existence and uniqueness of the positive solutions to semilinear elliptic system {△u+λf(u,v)=0,x∈Ω △u+λg(u,v)=0,x∈Ω u(x)+v(x)=0,x∈δΩ where λ〉0,Ω is a bounded smooth domain. Here f, g are real-valued functions defined on R2:=[0,∞)×[0,∞) and satisfy some conditions.
