摘　　要：在单值映象与集值映象相容或次相容的条件下,给出了完备凸度量空间中集值映象对于单值映象存在公共不动点的一个充分条件,改进和推广了文[1-4]中的已知结果。Under the conditions of compatibility or sub-compatibility between a single-valued mapping and asset-val- ued mapping, a sufficient condition for set-valued mapping pair and single-valued mapping which have the common fixed point in complete convex metric space are given .Some known result are improved and generalized.

关 键 词：集值映象 公共不动点 凸度量空间
