摘要:

用山路定理和迭代方法讨论一类带梯度项椭圆方程Dirichlet问题非平凡解的存在性, 在右端非线性项渐近线性增长的情形下证明了该问题正解和负解的存在性.

关键词: 带梯度项椭圆方程, 山路定理, 迭代方法

Abstract:

We considered the existence of nontrivial solution of Dirichlet problem for a class of  elliptic equation with gradient term by applying mountain pass theorem and iterative method, and we obtain the existence of positive and negative solutions for this problem with  asymptotically linear growth of rigthand side nonlinear term.

Key words: elliptic equation with dependence on the gradient, mountain pass theorem, iterate methods
