Set-valued Prešić-Ćirić type contraction in 0-complete partial metric spaces

Abstract

The purpose of this paper is to introduce theset-valued Prešić-Ćirić type contraction in0-complete partial metric spaces and to prove some coincidence andcommon fixed point theorems for such mappings in product spaces,in partial metric case. Results of this paper extend, generalizeand unify several known results in metric and partial metricspaces. An example shows how the results of this paper can be usedwhile the existing one cannot.
