摘要: 通过构造一个特殊的算子,将脉冲问题转化为连续性问题,然后利用锥拉伸和锥压缩不动点定理,研究Banach空间中一类二阶脉冲微分方程组边值问题,得到多重正解的存在性定理。

关键词: 脉冲微分方程组, 边值问题, , 多重正解

Abstract: By creating a special operator, the impulsive problem is transformed into a continuity problem. Then, we use the fixed point theorem of cone expansion and compression to investigate the boundary value problem of a second-order nonlinear impulsive differential system. Consequently, we confirm the existence of multiple positive solutions.

Key words: impulsive differential system, boundary value problem, cone, multiple positive solutions
