摘要

本文分析了如下非线性椭圆方程组解的存在性:\begin{equation*} \left\{ \begin{array}{rcll} -\Delta u & = & v^q+\a g & \text{in }\Omega , \\ -\Delta v& = &|\nabla u|^{p}+\l f &\text{in }\Omega , \\ u=v&=& 0 & \text{on }\partial \Omega ,\\ u,v& \geq & 0 & \text{in }\Omega, \end{array}% \right. \end{equation*} 其中 Ω\Omega\ren\ren 中的有界区域,p1p\ge 1q>0q>0pq>1pq>1f,gf,g 是满足附加假设的非负可测函数,\a,\l0\a, \l\ge 0。作为推论,我们证明了在 f~\tilde{f}\l~\tilde{\l} 的适当条件下,对于所有 p>1p>1,四阶问题 \begin{equation*} \left\{ \begin{array}{rcll} \Delta^2 u & = &|\nabla u|^{p}+\tilde{\l} \tilde{f} &\text{in }\Omega , \\ u=\D u&=& 0 & \text{on }\partial \Omega ,\\ \end{array}% \right. \end{equation*} 存在解。
