A Generalization of a Greguš Fixed Point Theorem in Metric Spaces.

We first introduce a new class of contractivemappings in the setting of metric spaces and then we present certain Greguš type fixed point theorems for such mappings. As an application, we derive certain Greguš type common fixed theorems. Our results extend Greguš fixed point theoreminmetric spaces and generalize and unify some related results in the literature. An example is also given to support our main result. [ABSTRACT FROM AUTHOR]
