ABSTRACT

This paper establishes new common fixed-point theorems for occasionally weakly compatible mappings in Menger spaces. By utilizing the probabilistic metric structure of Menger spaces and suitable contractive conditions, sufficient conditions are derived for the existence and uniqueness of common fixed points for a class of self-mappings. The results significantly extend several existing common fixed-point theorems by employing occasional weak compatibility, which is strictly weaker than conventional compatibility conditions. A unified framework is developed to address common fixed point problems in probabilistic metric spaces, and the obtained results are shown to encompass a number of established results as special cases. Furthermore, appropriate corollaries are presented to highlight the scope, generality, and applicability of the proposed theorems.
