Caristi's fixed point theorem in probabilistic metric spaces
نویسندگان
چکیده
In this work, we define a partial order on probabilistic metric spaces and establish some new Caristi's fixed point theorems Ekeland's variational principle for the class of (right) continuous Archimedean t-norms. As an application, answer to Kirk's problem in is given.
