摘 要: | 研究n维欧氏空间中有界光滑区域上具有非线性边界条件的椭圆方程正解的存在性问题。假设方程有一个正的上解,且0为方程的一个下解,则可以构造一个非减序列。根据极值原理、线性Robin问题解的唯一性,使用牛顿迭代法就可以找到问题的一个正解。 |
关 键 词: | 椭圆方程;正解;非线性边界条件;上、下解;牛顿迭代法 |

Abstract: | This paper deals with the existence of positive solution of elliptic equation with nonlinear boundary condition in a smooth bounded domain in 瘙}�n.Assuming the existence of a positive supersolution, and 0 is a subsolution, then a nondecreasing sequence is obtained. The existence result is obtained by the maximum principle, unique solvability of the linear Robin problem and Newton’s method of iteration. |
Key words: | elliptic equation; positive solution; nonlinear boundary condition; super, sub�solution; Newton’s method of iteration |
