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.

A new generalization of the Banach contraction principle [PDF]

open access: yesJournal of Inequalities and Applications, 2014
Denote by \(\Theta\) the class of all functions \(\theta:(0,\infty)\to (1,\infty)\) satisfying \begin{itemize} \item[(i)] \(\theta\) is non-decreasing, \item[(ii)] \(\theta(t_n)\to 1\) if and only if \(t_n\to 0\), \item[(iii)] \(\exists r\in (0,1)\), \(\exists s\in (0,\infty]\), such that \(\lim_{t\to 0+}(\theta(t)-1)/(t^r)=s\).

Ulam-Hyers Stability and Well-Posedness of Fixed Point Problems for α-λ-Contraction Mapping in Metric Spaces

open access: yesAbstract and Applied Analysis, 2014
We study Ulam-Hyers stability and the well-posedness of the fixed point problem for new type of generalized contraction mapping, so called α-λ-contraction mapping.

On Existence of Solutions of Impulsive Nonlinear Functional Neutral Integro-Differential Equations With Nonlocal Condition

open access: yesDemonstratio Mathematica, 2015
In the present paper, we investigate the existence, uniqueness and continuous dependence of mild solutions of an impulsive neutral integro-differential equations with nonlocal condition in Banach spaces. We use Banach contraction principle and the theory

Positive Solutions for Nonlinear Integro-Differential Equations of Mixed Type in Banach Spaces

open access: yesAbstract and Applied Analysis, 2013
We establish some new existence theorems on the positive solutions for nonlinear integro-differential equations which do not possess any monotone properties in ordered Banach spaces by means of Banach contraction mapping principle and cone theory based ...

Fixed-Point Theorems for θ−ϕ-Contraction in Generalized Asymmetric Metric Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020
In the last few decades, a lot of generalizations of the Banach contraction principle had been introduced. In this paper, we present the notion of θ-contraction and θ−ϕ-contraction in generalized asymmetric metric spaces to study the existence and ...

Further generalizations of the Banach contraction principle [PDF]

open access: yesJournal of Inequalities and Applications, 2014
AbstractWe establish a new fixed point theorem in the setting of Branciari metric spaces. The obtained result is an extension of the recent fixed point theorem established in Jleli and Samet (J. Inequal. Appl. 2014:38, 2014).

Maximal ideals in the algebra of operators on certain Banach spaces. [PDF]

open access: yes, 2002
For a Banach space $\mathfrak{X}$, let $\mathcal{B}(\mathfrak{X})$ denote the Banach algebra of all continuous linear operators on $\mathfrak{X}$. First, we study the lattice of closed ideals in $\mathcal{B}(\mathfrak{J}_p)$, where $1 < p < \infty$ and $\
