摘要: 该文完全去掉了[1]中对Sturm-Liouville两点边值问题进行先验估计时,△为单点集这一条件,从而本质上改进了[1]中非平凡解的存在性定理.

关键词: 先验估计, 拓扑度, 非平凡解

Abstract: In this paper,one important condition used to make the prior estimate in[1] is e-liminated,so the existence results for nontrivial solutions of the superlinear Sturm-Liouville twopoint boundary value problems are essentially improved.

Key words: The prior estimate, topological degree, nontrivial solutions
