The Existence of Fixed Points for Nonlinear Contractive Maps in Metric Spaces with w-Distances
نویسندگان
چکیده
Branciari 1 established a fixed point result for an integral type inequality, which is a generalization of Banach contraction principle. Kada et al. 2 introduced and studied the concept of w-distance on a metric space. They give examples of w-distances and improved Caristi’s fixed point theorem, Ekeland’s -variational’s principle, and the nonconvex minimization theorem according to Takahashi see many useful examples and results on wdistance in 2–5 and in references therein . Kada et al. 2 defined the concept of w-distance in a metric space as follows.

Fixed point of generalized contractive maps on S^{JS}- metric spaces with two metrics
In this paper we prove existence of fixed point theorems for Z-contractive map, Geraghty type contractive map and interpolative Hardy-Rogers type contractive mapping in the setting of SJS- metric spaces with two metrics. Examples are constructed to high light the significance of newly obtained results.
متن کاملThe Existence Theorem for Contractive Mappings on $wt$-distance in $b$-metric Spaces Endowed with a Graph and its Application
In this paper, we study the existence and uniqueness of fixed points for mappings with respect to a $wt$-distance in $b$-metric spaces endowed with a graph. Our results are significant, since we replace the condition of continuity of mapping with the condition of orbitally $G$-continuity of mapping and we consider $b$-metric spaces with graph instead of $b$-metric spaces, under which can be gen...
متن کاملCoupled coincidence point and common coupled fixed point theorems in complex valued metric spaces
In this paper, we introduce the concept of a w-compatible mappings and utilize the same to discuss the ideas of coupled coincidence point and coupled point of coincidence for nonlinear contractive mappings in the context of complex valued metric spaces besides proving existence theorems which are following by corresponding unique coupled common fixed point theorems for such mappings. Some illus...

متن کاملContractive maps in Mustafa-Sims metric spaces
The xed point result in Mustafa-Sims metrical structures obtained by Karapinar and Agarwal[Fixed Point Th. Appl., 2013, 2013:154] is deductible from a corresponding one stated in terms ofanticipative contractions over the associated (standard) metric space.
