摘要
运用Leggett-Williams不动点定理,研究了二阶脉冲微分方程组四点边值问题非负解的存在性,得到了边值问题3个非负解存在的充分条件.
Based on Leggett-Williams fixed-point theorem,the existence of nonnegative solutions of four-point boundary value problem for second-order system of impulsive differential equations was studied.The sufficient conditions for the existence of three nonnegative solutions of the boundary value problem were presented.
