摘要:

用LeraySchauder非线性抉择和更一般的锥不动点定理研究奇异二阶方程组边值问题两个正解的存在性, 给出了正解存在的充分条件, 并举例说明了所得结果.

关键词: 两点边值问题, 两个正解, LeraySchauder非线性抉择, 锥不动点定理, 方程组

Abstract:

We investigated the existence of two positive solutions to singular boundary value problems using LeraySchauder alter
native theorem and other fixed point theorems in cones, obtained its sufficient conditions and gave an example to explain our results.

Key words: twopoint boundary problems, twin positive solutions; LeraySchauder alternative, fixed point theorems, differential systems
