在G-度量空间中,利用自映像对相容和次相容的条件,讨论了G-度量空间中一类压缩映像的公共不动点的存在性与唯一性,得到一个新的公共不动点的定理,其结果改进和发展了已有文献的相关结果。

By using the compatible and subcompatible conditions of self-mapping pair in G-metric spaces,the existence of common fixed point for a class of contract mappings in G-metric spaces was discussed.A new common fixed theorem is obtained.Some relative results are largely improved and extended by the obtained ones.
