高阶拟线性椭圆方程的正解
Positive solutions of higher order quasilinear elliptic equation in exterior domains
【摘要】 讨论拟线性椭圆方程Δ2 U = f(x,u,u), x ∈Ωα其中Ωα= {x ∈ R N||x| > α}, N ≥2,α> 0, u = ( ux1 ,…, ux N ),且Δ2 = ·,在一定条件下,上述方程有无穷多个正解,并且上述方程在边界条件 U|Ωα= 0 下仍然如此。
【Abstract】 The existence of infinitely many positive solutions of quasilinear elliptical differential equation Δ 2U=f(x,u,u), x∈Ω α is proved, when throughout exterior domains Ω α={x∈R N||x|>α},N≥2,α>0, where x=(x 1,x 2,…,x N), u=(ux 1,ux 2,…,ux N),and Δ 2=·.
