ON A QUASI FIXED-POINT THEOREM [PDF]
Bulletin of the Korean Mathematical Society, 2003 In the paper under review, the author generalizes, in some aspects, the quasi fixed-point theorem due to \textit{I. Lefebvre} [Set-Valued Anal. 9, No. 3, 273--288 (2001; Zbl 0986.54051)] and proves the following Theorem. Let \(I\) and \(J\) be any index sets.

Generalized fixed point theorems on metric spaces [PDF]
Mathematica Moravica, 2022 In this paper, we establish some fixed point theorems for single valued and multi-valued mappings on a complete metric space. Suzuki's and some other fixed point theorems are generalized by taking a more general contractive condition for single valued ...

A Generalization of b-Metric Space and Some Fixed Point Theorems
, 2017 In this paper, inspired by the concept of b-metric space, we introduce the concept of extended b-metric space. We also establish some fixed point theorems for self-mappings defined on such spaces.

Generalized 𝜶-𝝍 Contractive Type Mappings and Related Fixed Point Theorems with Applications
Abstract and Applied Analysis, 2012 We establish fixed point theorems for a new class of contractive mappings. As consequences of our main results, we obtain fixed point theorems on metric spaces endowed with a partial order and fixed point theorems for cyclic contractive mappings. Various

Fixed point theorems for F-expanding mappings
Fixed Point Theory and Applications, 2017 Recently, Wardowski (Fixed Point Theory Appl. 2012:94, 2012) introduced a new concept of F-contraction and proved a fixed point theorem which generalizes the Banach contraction principle.

Fixed point theorems for generalized weakly contractive mappings in metric spaces with applications
Fixed Point Theory and Applications, 2018 In this paper, motivated and inspired by Samet et al., we introduce the notion of generalized weakly contractive mappings in metric spaces and prove the existence and uniqueness of fixed point for such mappings, and we obtain a coupled fixed point ...

Fixed Point Theorems via α-ϱ-Fuzzy Contraction
Axioms, 2019 Some well known results from the existing literature are extended and generalized via new contractive type mappings in fuzzy metric spaces. A non trivial supporting example is also provided to demonstrate the validity of the obtained results.

Fixed point theorems for various types of F-contractions in complete b-metric spaces
, 2018 We generalize various types of F -contractions defined by Wardowski, Vetro and others to b-metric spaces and prove fixed point theorems for them. The examples given show that these generalizations extend the existing results in a significant way.

Almost fixed point theorems [PDF]
Proceedings of the American Mathematical Society, 1988 A closed cover version of Hazewinkel and van de Vel’s theorem on the existence of γ \gamma -almost fixed points for set-valued functions and for real Hausdorff topological vector spaces is proved. Generalizations of well-known fixed point theorems of the Schauder-Tychonoff type are presented.

Fixed point theorems for Kannan type mappings
, 2017 In this note, we prove some fixed point theorems for Kannan type mappings. We will use the additional conditions as compactness or asymptotic regularity or involutions.
