Fixed point theorems for φ-contractions
*Correspondence: [email protected] 1School of Natural Sciences, National University of Sciences and Technology, H-12, Islamabad, Pakistan Full list of author information is available at the end of the article Abstract This paper deals with the fixed point theorems for mappings satisfying a contractive condition involving a gauge function φ when the underlying set is endowed with a b-met...
متن کاملApproximate fixed point theorems for Geraghty-contractions
The purpose of this paper is to obtain necessary and suffcient conditionsfor existence approximate fixed point on Geraghty-contraction. In this paper,denitions of approximate -pair fixed point for two maps Tα , Sα and theirdiameters are given in a metric space.
متن کاملQuadruple fixed point theorems for nonlinear contractions
The notion of coupled fixed point is introduced by Gnana-Bhaskar and Lakshmikantham. Very recently, the concept of tripled fixed point was introduced by Berinde and Borcut. In this manuscript, a quadruple fixed point is considered and some new related fixed point theorems are obtained. We also give some examples to illustrate our results. © 2012 Elsevier Ltd.

متن کاملNew result on fixed point theorems for φ-contractions in Menger spaces
Very recently, Fang (Fuzzy Sets Syst. 267:86-99, 2015) gave some fixed point theorems for probabilistic φ-contractions in Menger spaces. Fang’s results improve the one of Jachymski (Nonlinear Anal. 73:2199-2203, 2010) by relaxing the restriction on the gauge function φ . In this paper, inspired by the results of Fang, we prove a new fixed point theorem for a probabilistic φ-contraction in Menge...
متن کاملCoupled Common Fixed Point Theorems for Φ-contractions in Probabilistic Metric Spaces and Applications
In this paper, we give some new coupled common fixed point theorems for probabilistic φ-contractions in Menger probabilistic metric spaces. As applications of the main results, we obtain some coupled common fixed point theorems in usual metric spaces and fuzzy metric spaces. The main results of this paper improve the corresponding results given by some authors. Finally, we give one example to i...
