中文摘要:

      研究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,利用Leggett-Williams不动点定理得到了方程三个非负解存在的充分条件.

英文摘要:

      The paper studies the existence of three nonnegative solutions to a type of three-point 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.
