Some Fixed Point Theorems for Prešić-Hardy-Rogers Type Contractions in Metric Spaces

摘要

We introduce some generalizations of Prešić type contractions and establish some fixed point theorems for mappings satisfying Prešić-Hardy-Rogers type contractiveconditions in metric spaces. Our results generalize and extend several known results in metric spaces. Some examples are included which illustrate the cases when new results can be applied while old ones cannot.
