摘　　要：本文在半序线性空间中建立了集值凹及凸算子等概念,讨论了在增算子的条件下,集值算子存在不动点的问题。In this paper the conceptions of set -valued u0 -concave and u0-convex operators in a partial order linear space is given. The author discusses the problems of fixed point for the set -valued increasing operators. Mang fixed point theorems are obtained. It is a generalized from single - valued operators to set -valued operators.
