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与单值映象存在公共不动点的一个充要条件和一个充分条件 。Under the conditions of compatibility or sub-compatibility between a single-valued mapping and a set-valued mapping,a necessary and sufficient condition and a sufficent condition for set-valued mapping pair and single-valued mapping which have the common fixed point in complete convex metric spaces are given. Some known results are improved and generalized.

关 键 词：凸度量空间 集值映象对 公共不动点 单值映象
