Recent developments about multivalued weakly Picard operators
(Belgian Mathematical Soc Triomphe, 2015)
In the present paper, considering a recent technique, which is used by Wardowski [24] for fixed points of single-valued mappings, we give a new and general class of multivalued weakly Picard operators on complete metric ...
Caristi's Type Mappings On Complete Partial Metric Spaces
(House Book Science-Casa Cartii Stiinta, 2013)
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 ...
