Fixed Point Results of Expansive Mappings in Metric Spaces

In this study, we introduce the concept of theta-expansive mapping in ordered metric spaces and prove a fixed point theorem for such mappings. We give some fixed point results for theta-expansive mapping in metric spaces and prove fixed point theorems for such mappings. These results extend the main results of many comparable results from the current literature. We also obtain a common fixed point theorem of two weakly compatible mappings in metric spaces. Finally, the examples are presented to support the new theorems and results proved.
