Caristi's Type Mappings On Complete Partial Metric Spaces
Citation
closedAccessAbstract
We introduce a new type of Caristi's mapping on partial metric spaces and show that a partial metric space is complete if and only if every Caristi mapping has a fixed point. From this result we deduce a characterization of bicomplete weightable quasi-metric spaces. Several illustrative examples are given.
