Relation-Theoretic Contraction Principle In Metric Spaces Using Multiplicative Contraction

open access: yesRatio Mathematica, 2023
Alam and Imdad have presented a novel application of the Banach contraction principle on a complete metric spaces with a binary relation. We have extended the concept of binary relation with the multiplicative contraction in a complete metric spaces.

Even Continuity and the Banach Contraction Principle [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
In 1967, Philip R. Meyers established a nice converse to the Banach Contraction Mapping Theorem. We provide a counterexample to one of his corollaries and show that if X is a metrizable topological space, f a continuous self-map on X such that: (a)f has a fixed point p which has a compact neighborhood; (b) f

Some fixed point results in complete generalized metric spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
The Banach contraction principle is the most important result. This principle has many applications and some authors was interested in this principle in various metric spaces as Brianciari.

On the existence of solutions for a higher order differential inclusion without convexity [PDF]

open access: yes, 2007
We prove a Filippov type existence theorem for solutions of a higher order differential inclusion in Banach spaces with nonconvex valued right hand side by applying the contraction principle in the space of the derivatives of solutions instead of the ...

A unified theory of cone metric spaces and its applications to the fixed point theory [PDF]

open access: yes, 2011
In this paper we develop a unified theory for cone metric spaces over a solid vector space. As an application of the new theory we present full statements of the iterated contraction principle and the Banach contraction principle in cone metric spaces ...

An application of Ramsey’s Theorem to the Banach Contraction Principle [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
One of the most fundamental fixed-point theorems is Banach’s Contraction Principle, of which the following conjecture is a generalization. Generalized Banach Contraction Conjecture (GBCC). Let

Existence of a solution for a nonlinear integral equation by nonlinear contractions involving simulation function in partially ordered metric space

open access: yesNonlinear Analysis, 2023
In a recent paper, Khojasteh et al. presented a new collection of simulation functions, said Z-contraction. This form of contraction generalizes the Banach contraction and makes different types of nonlinear contractions.

Projective metrics and contraction principles for complex cones [PDF]

open access: yes, 2008
In this article, we consider linearly convex complex cones in complex Banach spaces and we define a new projective metric on these cones. Compared to the hyperbolic gauge of Rugh, it has the advantage of being explicit, and easier to estimate.

Existence and uniqueness of solutions for a class of nonlinear integro-differential equations on unbounded domains in Banach spaces

open access: yesAdvances in Difference Equations, 2018
In this paper, the existence and uniqueness of solutions for a class of nonlinear integro-differential equations on unbounded domains in Banach spaces are established under more general conditions by constructing a special Banach space and using cone ...

Boundary controllability of impulsive nonlinear fractional delay integro-differential system

open access: yesCogent Engineering, 2016
By using the strongly continuous semigroup theory and the Banach contraction principle, we study the boundary controllability of time varying delay impulsive nonlinear fractional integrodifferential system in Banach spaces.
