In this paper, we introduce the concept of a w-compatible mappings and utilize the same to discuss the ideas of coupled coincidence point and coupled point of coincidence for nonlinear contractive mappings in the context of complex valued metric spaces besides proving existence theorems which are following by corresponding unique coupled common fixed point theorems for such mappings. Some illus...

In this paper we obtain a unique common xed point theorem for sixweakly compatible mappings in G-metric spaces.

The aim of this paper is to introduce the concepts of compatible mappings and compatible mappings of type (R) in non-Archimedean Menger probabilistic normed spaces and to study the existence problems of common fixed points for compatible mappings of type (R), also, we give an applications by using the main theorems.

in this paper, we shall introduce the fuzzyw-distance, then prove a common fixed point theorem with respectto fuzzy w-distance for two mappings under the condition ofweakly compatible in complete fuzzy metric spaces.

Upper ontologies are interesting because describing and representing concepts that can be used across various domains (as opposed to domain ontologies). This feature may enable increased correctness of mappings between domain ontologies, conceptual schema and languages. Unfortunately, there exist various upper ontologies and it is quite difficult to decide or to assess which of them should be u...
