Path--Averaged Contractions: A New Generalization of the Banach Contraction Principle

open access: yes
We introduce a novel class of self-mappings on metric spaces, called \textbf{PA-contractions} (Path-Averaged Contractions), defined by an averaging condition over iterated distances. We prove that every continuous PA-contraction on a complete metric space has a unique fixed point, and the Picard iterates converge to it.

Regularity of solutions of Sobolev type semilinear integrodifferential equations in Banach spaces

open access: yesElectronic Journal of Differential Equations, 2003
In this article, we prove the existence of mild and classical solutions of Sobolev type semilinear integrodifferential equations of the form $$ frac{d}{dt}[Ex(t)] = A[x(t)+int_0^tF(t-s)x(s)ds]+f(t,x(t)) $$ in Banach spaces.

Perimetric contraction on quadrilaterals and related fixed point results [PDF]

open access: yes
In this article, we introduce a four-point analogue of Banach-type, Kannan-type, and Chatterjea-type contractions, and examine their properties. We establish sufficient conditions under which these mappings achieve fixed points in a complete metric space.

Banach Fixed Point Theorem

open access: yes, 2020
U ovom završnom radu rećićemo nešto o Banachovom kontrakcijskom principu koji je poznat pod imenom Banachovom teorem o fiksnoj točki. Denirat ćemo potpunost metrič- kih prostora i navesti neke primjere.

Existence of non-oscillatory solutions to first-order neutral differential equations

open access: yesElectronic Journal of Differential Equations, 2016
This article presents sufficient conditions for the existence of non-oscillatory solutions to first-order differential equations having both delay and advance terms, known as mixed equations. Our main tool is the Banach contraction principle.

Quasicontraction Mappings in Modular Spaces without Δ2-Condition

open access: yesFixed Point Theory and Applications, 2008
As a generalization to Banach contraction principle, Ćirić introduced the concept of quasi-contraction mappings. In this paper, we investigate these kinds of mappings in modular function spaces without the -condition.

Genelleştirilmiş banach-büzülme prensibi kullanılarak yeni sabit nokta teoremlerinin elde edilmesi [PDF]

open access: yes, 2019
In this study, a new three step iterative algorithm was introduced with the help of Jungck-contraction principle which is one of the remerkable generalizations of Banach-contraction principle. Also, the convergence and stability results were obtained for
