Cyclic G‐Ω-Weak Contraction-Weak Nonexpansive Mappings and Some Fixed Point Theorems in Metric Spaces

open access: yesAbstract and Applied Analysis, 2021
This paper introduces novel concepts of joint Y,Z cyclic G‐ΩS,T,abef-weak contraction and joint Y,Z cyclic G‐ΩS,T,abef-weak nonexpansive mappings and then proves the existence of a unique common fixed point of such mappings in case of complete and ...

Some Fixed Point Theorems Via Combination of Weak Contraction and Caristi Contractive Mapping

open access: yesAnnales Mathematicae Silesianae, 2021
In this paper we introduce some new types of contractive mappings by combining Caristi contraction, Ćirić-quasi contraction and weak contraction in the framework of a metric space.

Some Fixed-Point Results for a -Weak Contraction in -Metric Spaces [PDF]

open access: yesAbstract and Applied Analysis, 2012
We introduce the concepts of a -weak contraction mapping of types and and we establish some fixed point theorems for a -weak contraction mapping of types and in complete -metric spaces. Our results generalize several well-known comparable results in

Periodic points for the weak contraction mappings in complete generalized metric spaces

open access: yesFixed Point Theory and Applications, 2012
In this article, we introduce the notions of (ϕ - φ)-weak contraction mappings and (ψ - φ)-weak contraction mappings in complete generalized metric spaces and prove two theorems which assure the existence of a periodic point for these two types of weak ...

On (α,φ)-weak Pata contractions

open access: yesMANAS: Journal of Engineering, 2022
In this paper, we give (α,φ)-weak Pata contractive mapping by using the simulation function and multivalued (α,φ)-weak Pata contractions and establish some fixed point results for such contractions.

Weak theta-phi-contraction and discontinuity

open access: yesThe Journal of Nonlinear Sciences and Applications, 2017
Summary: In this paper, we introduce the notion of weak \(\theta\)-\(\phi\)-contraction ensuring a convergence of successive approximations but does not force the mapping to be continuous at the fixed point. Thus, we answer one more solution to the open question raised by \textit{B. E. Rhoades} [Contemp. Math. 72, 233--245 (1988; Zbl 0649.54024)].

Coupled Fixed Point Theorems for Weak Contraction Mappings under F-Invariant Set

open access: yesAbstract and Applied Analysis, 2012
We extend the recent results of the coupled fixed point theorems of Cho et al. (2012) by weakening the concept of the mixed monotone property. We also give some examples of a nonlinear contraction mapping, which is not applied to the existence of the ...

On Multi-valued Weak Contraction Mappings

open access: yesJournal of Mathematics Research, 2011
In this paper, we study fixed point theorems for multi-valued weak contractions. We show that the Picard projection iteration converges to a fixed point, give a rate of convergence and generalize Collage theorem. This work includes results on multi-valued contraction mappings studied by (Kunze, H.E., La Torre, D.
