摘要
利用锥上的不动点指数定理研究了一类二阶方程组特征值边值问题正解的存在性,在λ充分小,f与g满足更广泛的条件下得到了两个正解,推广和改进了原有的结果.
This paper studies some boundary value problems of second-order systems eigenvalue. When λ is small enough, the positive solutions are obtained by utilizing the theory of fixed point indexunder the extensive condition. The results of this paper partially improve the former corresponding work.
