摘　　要：本文是文 [2 ]的继续 ,先给出集值 u0 -增算子的概念 ,然后在序条件下讨论了 u0 -凹 (凸 )算子不动点的若干性质 ,得出 [1。In this paper, we define the u 0 increasing operator and obtain some property about fixed points of multi valued u 0 concave(convex) operators (in[2]) in ordered Banach space. The corresponding results of [1,3] are extended in the set valued case.
