Coincidence point theorems in quasi-metric spaces without assuming the mixed monotone property and consequences in G-metric spaces
(Springer International Publishing, 2014-09)
In this paper, we present some coincidence point theorems in the setting of quasi-metric spaces that can be applied to operators which not necessarily have the mixed monotone property. As a consequence, we particularize ...
An approach version of fuzzy metric spaces including an ad hoc fixed point theorem
(Springer, 2015-02-27)
In this paper, inspired by two very different, successful metric theories such us the real view-point of Lowen's approach spaces and the probabilistic field of Kramosil and Michalek's fuzzymetric spaces, we present a family ...
