摘要:

研究一类椭圆方程组正解的唯一性. 运用变换技巧和极值原理, 在确定的条件下证明了有关解的两个递归不等式, 并取极限得到了该问题的唯一正解. 结果表明, 在更弱的条件下, 该问题没有非常值正解.

关键词: 椭圆方程组, 正解, 唯一性

Abstract:

This paper deals with the uniqueness of positive solutions of the Neumann problem for an elliptic system. With the help of transformation technique and maximal principle, we proved two inequalities of solutions under a definite condition, and then obtained the uniqueness of positive solution by taking the limit for them, which also shows that under more weak conditions, the problem has no any positive nonconstant solution.

Key words: elliptic system, positive solution, uniqueness
