摘要
利用不动点定理,通过构造3个泛函,研究一类非线性项中含有一阶导数的二阶脉冲微分方程积分边值问题多个非负解的存在性.在较弱的条件下,得到了该脉冲边值问题具有3个非负解的多解定理.
With the aid of the fixed point theorem in a cone,we studied the existence of multiple nonnegative solutions to a type of the boundary value problems of second-order impulsive differential equations with integral boundary conditions and with the nonlinear term containing the first-order derivative by constructing three functional.The theorem for the existence of at least three nonnegative solutions was obtained under the weaker conditions.
