An Extension of the Contraction Principle [PDF]

open access: yesJournal of Theoretical Probability, 2004
The ``contraction principle'' is about large deviations; the basic definitions figure in [\textit{A. Dembo} and \textit{O. Zeitouni}, ``Large deviation techniques and applications''. 2nd ed. (1998; Zbl 0896.60013)]. Its statement is (C). Let \((X_{n})\) satisfy the large deviation principle with good rate function \(I\) (defined on the metric space \({\

Generalized contraction principle under relatively weaker contraction in partial metric spaces

open access: yesAdvances in Difference Equations, 2019
In this paper, we introduce the concept of a generalized weak (ϕ,R) $(\phi,\mathcal{R})$-contraction and employ this to prove some fixed point results for self-mappings in partial metric spaces endowed with a binary relation R $\mathcal{R}$.

A generalization of contraction principle

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
In this paper, a generalized mean value contraction is introduced. This contraction is an extension of the contractions of earlier researchers and of the generalized mean value non-expansive mapping.

Krasnoselskii's theorem in generalized Banach spaces and application

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
The purpose of this paper is to extend Krasnoselskii's fixed point theorem to the case of generalized Banach spaces for singlevalued and multivalued operators.

A discrete fixed point theorem of Eilenberg as a particular case of the contraction principle

open access: yesFixed Point Theory and Applications, 2004
We show that a discrete fixed point theorem of Eilenberg is equivalent to the restriction of the contraction principle to the class of non-Archimedean bounded metric spaces.

Generalizations of Banach's contraction principle and Kannan and Chatterjea's theorems for cyclic and non-cyclic mappings [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
‎Two interesting extensions of Banach contraction principle to mappings that don't to be continuous‎, ‎are Kannan and Chatterjea's theorems‎. ‎Before this‎, ‎in the cyclical form‎, ‎extensions of these two theorems and Banach contraction principle were ...
