摘要
讨论了一类脉冲周期边值问题多个正解的存在性,首先把脉冲微分方程解的存在性转化为等价的算子方程的不动点的存在性,然后利用Leggett-Willams不动点定理,获得了此边值问题至少3个正解的存在性.
The existence of multiple positive solutions to a pulse periodic boundary value problems is discused.First,changing the existence of the solutions into the equivalent conversion operator equation of the existence of the fixed point,then using Leggett-Willams fixed point theorem,at least three of the existence of positive solutions to the boundary value problems are obtained.
