讨论一类具有Dirichlet边值的半线性椭圆方程{-△u=λ(u^p-u^q),x∈Ω u=0,x∈δΩ其中Ω包含R^n,主要利用Liouville及re—scaling等方法探讨,当n=2,3时,这类方程正稳定解的唯一性.
We mainly consider the uniqueness of the stable positive solution to a semilinear elliptic equation with Dirichlet boundary condition {-△u=λ(u^p-u^q),x∈Ω u=0,x∈δΩ Meanwhile, in this paper, we show the unique about stable solution for a special semilinear elliptic equation when Ω being to R^n(n = 2, 3), by Liouville and re-scaling technique.
