Random fixed point theorems for asymptotic 1-set contraction operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Random fixed point theorems for condensing, 1-set contraction selfless are known. But no random fixed point theorem for more general asymptotic 1-set contraction selfmaps is yet available.

Some fixed point theorems in b-metric-like spaces

open access: yes, 2015
In this work, some fixed point and common fixed point theorems are investigated in b-metric-like spaces. Some of our results generalize related results in the literature.

Unique Fixed Point Theorems for Generalized Contractive Mappings in Partial Metric Spaces

open access: yes, 2015
We establish some unique fixed point theorems in complete partial metric spaces for generalized weakly -contractive mappings, containing two altering distance functions under certain assumptions.

On a fixed point theorem of Kirk

open access: yesJournal of Mathematical Analysis and Applications, 2005
The author presents a new short and simple proof of the following theorem essentially due to \textit{W. A. Kirk} [J. Math. Anal. Appl. 277, No. 2, 645--650 (2003; Zbl 1022.47036)]. Let \((X, d)\) be a complete metric space, \(T: X\to X\) continuous map and \(\{\phi_n\}\) a sequence of continuous functions such that \(\phi_n: [0, \infty)\to [0, \infty)\)

Some Comments on Edelstein’s Fixed Point Theorems in ν-Generalized Metric Spaces [PDF]

open access: yes, 2018
We study deeply two fixed point theorems in n-generalized metric spaces. The two theorems are generalizations of the famous, Edelstein’s fixed point theorem in compact metric ...

Some Integral Type Fixed Point Theorems for Non-Self-Mappings Satisfying Generalized (ψ,φ)-Weak Contractive Conditions in Symmetric Spaces

open access: yesAbstract and Applied Analysis, 2014
The aim of this paper is to obtain some new integral type fixed point theorems for nonself weakly compatible mappings in symmetric spaces satisfying generalized (ψ,φ)-contractive conditions employing the common limit range property.

On the Brouwer fixed point theorem

open access: yesTopology and its Applications, 2002
The author studies the Brouwer-type fixed point theorem for multivalued mappings which are continuous with respect to the Borsuk continuity metric and have spheric-type values. By using deep topological methods, the fixed-point problem is expressed in terms of sphere bundles over manifolds. New methods in the fixed-point problem are presented.

Approximate Fixed Point Theorems in Banach Spaces with Applications in Game Theory [PDF]

open access: yes
In this paper some new approximate fixed point theorems for multifunctions in Banach spaces are presented and a method is developed indicating how to use approximate fixed point theorems in proving the existence of approximate Nash equilibria for non ...
