New Unique Common Fixed Point Results for Four Mappings with Ф-Contractive Type in 2-Metric Spaces

摘要

In this paper, some new unique common fixed points for four mappings satisfying Ф-contractive conditions on non-complete 2-metric spaces are obtained, in which the mappings do not satisfy continuity and commutation. The main results generalize and improve many well-known and corresponding conclusions in the literatures.
