On a New Generalization of Banach Contraction Principle with Application [PDF]

open access: yesMathematics, 2019
The main purpose of the current work is to present firstly a new generalization of Caristi’s fixed point result and secondly the Banach contraction principle. An example and an application is given to show the usability of our results.

Some Analogies of the Banach Contraction Principle in Fuzzy Modular Spaces [PDF]

open access: yesThe Scientific World Journal, 2013
We established some theorems under the aim of deriving variants of the Banach contraction principle, using the classes of inner contractions and outer contractions, on the structure of fuzzy modular spaces.

Periodic boundary value problems for nonlinear impulsive fractional differential equation [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, we investigate the existence and uniqueness of solution of the periodic boundary value problem for nonlinear impulsive fractional differential equation involving Riemann-Liouville fractional derivative by using Banach contraction principle.

A Generalization of Banach's Contraction Principle [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
Let T : M → M T:M \to M be a mapping of a metric space ( M , d ) (M,d) into itself. A mapping T T will be called a quasi-contraction iff d ( T x , T y ) ⩽ q

Equivalent results to Banach’s contraction principle

open access: yesAnnals of Functional Analysis, 2017
We present two versions of the well-known Banach contraction principle: one in the context of extended metric spaces for which the distance mapping is allowed to be infinite, the other in the context of metric spaces endowed with a compatible binary relation.

On the Picard – Lindelöf Argument and the Banach – Caccioppoli Contraction Mapping Principle

open access: yesRegular and Chaotic Dynamics
The aim of this note is to present the simple observation that a slight refinement of the Contraction Mapping Principle allows one to recover the precise convergence rate in the Picard-Lindelöf Theorem.

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 ...

A Coupled Random Fixed Point Result With Application in Polish Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle.
