TY - JOUR TI - Fixed point theorem for compatible mappings in intuitionistic fuzzy 3-metric spaces AU - Abu-Donia Hassan M AU - Atia Hany A AU - Khater Omnia M. A. JN - Thermal Science PY - 2020 VL - 24 IS - 11 SP - 371 EP - 376 PT - Article AB - In this paper, we introduced the concept of weak compatible of type (α) and asymptotically regular defined on intuitionistic fuzzy 3-metric space and proved the uniqueness and existence the fixed point theorem for five mappings from a complete intuitionistic fuzzy 3-metric space into itself under weak compatible of type (α) and asymptotically regular. The used definitions and theorem show the practice of our main idea.
