E.Liz和J.J.Nieto有关定理的注记

Remark on E.Liz and J.J.Nieto's theorem

本文讨论了一阶积分 -微分周期边值问题 ,指出了 E.Liz和 J.J.Nieto关于该问题的唯一性结果在上解、下解不相等时必不成立 ;同时本文的定理 2在不同的单调性条件下给出了该问题解集的结构。

The main results of this paper improve and extend the results obtained by E.Liz and J.J.Nieto.Meanwhile we give the structure of the set of solutions for PBVP of oneth order integro differential equations under different monotoncity assumptions.
