上下解和单调迭代法
1.
By means of the method of upper and lower solutions and monotone iterative technique, the existence of maximal and minimal solutions of the paratrized boundary value problems for first order impulsive differential equations are established under the assumption that correponding functions satisfy the onesided Lipschitz condition.
利用上下解和单调迭代法,讨论了带参数的一阶脉冲微分方程,获得了单边Lipschitz条件下这类方程边值问题的解的存在性。
