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.

Remarks on Recent Fixed Point Theorems
Fixed Point Theory and Applications, 2010 Coincidence and fixed point theorems for a new class of contractive, nonexpansive and hybrid contractions are proved. Applications regarding the existence of common solutions of certain functional equations are also discussed.

Near Fixed Point Theorems in Hyperspaces
Mathematics, 2018 The hyperspace consists of all the subsets of a vector space. It is well-known that the hyperspace is not a vector space because it lacks the concept of inverse element. This also says that we cannot consider its normed structure, and some kinds of fixed

Fixed Point Theorems for Multivalued Mappings Involving α-Function
Abstract and Applied Analysis, 2014 We obtain some fixed point theorems with error estimates for multivalued mappings satisfying a new α-ψ-contractive type condition. Our theorems generalize many existing fixed point theorems, including some fixed point theorems proved for α-ψ-contractive ...

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 ...

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.

Some Fixed Point Theorems in Fuzzy n-Normed Spaces [PDF]
, 2010 The main purpose of this paper is to study the existence of a fixed points in fuzzy n-normed spaces. we proved our main results, a fixed point theorem for a self mapping and a common fixed point theorem for a pair of weakly compatible mappings on fuzzy n-

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.

Communications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1984 The authors' main result is the following: Let (X,d) be a complete metric space and \(f: X\to X\) a self-mapping. If for x,y\(\in X\) and \(p>0\) the inequality \[ d(T^{2p}x,T^{2p}y)\leq a_ 1d(T^ px,T^{2p}x)+a_ 2d(T^ py,T^{2p}y)+a_ 3d(T^ px,T^ py) \] with \(a_ 1,a_ 2,a_ 3\geq 0\) and \(a_ 1+a_ 2+a_ ...
