摘要
利用摄动方法和构造比较函数,研究了一类含有加权梯度项的非线性椭圆方程Δu=b(x)eu±c(x)︱▽uq,x∈Ω;u︱Ω=+∞的爆破解的渐近行为,其中Ω是RN中的有界光滑区域,q≥0,权函数b(x),c(x)∈Cα(Ω),α∈(0,1),且是Ω内的非负函数.
By a perturbation method and construction comparison functions, the behavior of large solutions near the boundary to nonlinear elliptic problems Δu=b(x)eu±c(x)︱▽uq,x∈Ω;u︱Ω=+∞ is studied, where 0 is a bounded N domain with smooth boundary in RN , q ≥ 0, the weight b(x),c(x)∈Cα(Ω),α∈(0,1), and are non-negative functions in Ω.
