Common Fixed Points of Expansive Mappings in Generalized Metric Spaces

Abstract

In this paper, we establish a common fixed point theorem for expansive mappings by using the concept of weakcompatibility in the setting of G -metric spaces. This result generalizes the result of Ahmed [2] from 2-metric spaces toG -metric spaces by removing the condition of sequential continuity of the mappings. Further, we generalize andextend the theorem of ?ahin and Telci [20] to G -metric spaces and thereby extending the theorem of Wang et al. [23]for a pair of mappings to G -metric spaces. Some comparative examples are constructed which illustrate the obtainedresults.
