On Some New Jungck–Fisher–Wardowski Type Fixed Point Results
(MDPI (Basel, Switzerland), 2020-12-10)
Many authors used the concept of F−contraction introduced by Wardowski in 2012 in order to define and prove new results on fixed points in complete metric spaces. In some later papers (for example Proinov P.D., J. Fixed ...
Caristi, Nadler and H + -Type Contractive Mappings and Their Fixed Points in θ-Metric Spaces
(MDPI (Basel, Switzerland), 2019-04-07)
A new proper generalization of metric called as θ -metric is introduced by Khojasteh et al. (Mathematical Problems in Engineering (2013) Article ID 504609). In this paper, first we prove the Caristi type fixed point theorem ...
