摘要: 研究了一类拟线性方程Neumann问题的梯度估计,通过选取适当的辅助函数,利用函数在极大值点的性质,证明了解的边界梯度估计有界。得到了方程中关于f依赖于x,u时Neumann问题的解的边界梯度估计。
Abstract:
The gradient estimation of a class of quasilinear equations Neumann problem is studied. By se-lecting appropriate auxiliary functions and using the properties of functions at maximum points, it is proved that boundary gradient estimation is bounded. The boundary gradient estimation of Neumann problem solution is obtained when f depends on x, u in the equation.
