在G-度量空間中,利用自映像對(duì)相容和次相容的條件,討論了G-度量空間中一類壓縮映像的公共不動(dòng)點(diǎn)的存在性與唯一性,得到一個(gè)新的公共不動(dòng)點(diǎn)的定理,其結(jié)果改進(jìn)和發(fā)展了已有文獻(xiàn)的相關(guān)結(jié)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.
