Radon–Nikodým indexes and measures of weak noncompactness

Journal of Functional Analysis, 2014
The authors introduce and study certain indices related to the Radon-Nikodým property in Banach spaces. Interesting quantitative versions of classic results in RNP are proved. Let \(E\) be a Banach space and \((\Omega,\Sigma,\mu)\) a complete probability space.

Measures of weak noncompactness in Banach spaces [PDF]

, 2009
Measures of weak noncompactness are formulae that quantify different characterizations of weak compactness in Banach spaces: we deal here with De Blasi's measure ω and the measure of double limits γ inspired by Grothendieck's characterization of weak ...

Existence of weak solutions for a boundary value problem of a second order ordinary differential equation

Boundary Value Problems, 2018
The aim of this paper is to investigate the existence of weak solutions for a boundary value problem of a second order differential equation. As the main tool, we apply a Krasnosel’skii type fixed point theorem in conjunction with the technique of ...

Nonemptyness and compactness of the solution set for fractional evolution inclusions with non-instantaneous impulses

Electronic Journal of Differential Equations, 2019
In this article, we consider the nonemptyness and compactness of the solution set for a class of fractional semilinear evolution inclusions with non-instantaneous impulses in Banach spaces. To achieve this we use fixed point theorems with semigroup

Asymptotic behavior for nonautonomous functional differential inclusions with measures of noncompactness [PDF]

, 2016
We study the asymptotic behavior of nonautonomous differential inclusions with delays in Banach spaces by analyzing their pullback attractors. Our aim is to give a recipe expressed by measures of noncompactness to prove the asymptotic compactness of the ...

Existence theory for nonlinear volterra integral and differential equations

Journal of Inequalities and Applications, 2001
In this paper we prove the existence theorems for the integrodifferential equation where in first part are functions with values in a Banach space and the integral is taken in the sense of Bochner. In second part are weakly–weakly sequentially

Fractional Differential Inclusions with Non Instantaneous Impulses in Banach Spaces

Results in Nonlinear Analysis, 2019
This paper is devoted to study the existence of solutions for a class of fractional differential inclusions with non instantaneous impulses involving the Caputo fractional derivative in a Banach space.
