一类二阶脉冲微分方程三点边值问题三个非负解的存在性
The paper studies the existence of three nonnegative solutions to a type of threepoint boundary value problem for second-order impulsive differential equations, and obtains the sufficient conditions for existence of three nonnegative solutions by means of the Leggett-Williams's fixed point theorem.
