Some Properties of Measures of Noncompactness in Paranormed Spaces [PDF]

Proceedings of the American Mathematical Society, 1988
This paper presents new properties of important measures of noncompactness in paranormed spaces. Using these properties some fixed point theorems for multivalued mappings in general topological vector spaces are obtained in a straightforward way.

Controllability problem for fractional impulsive integrodifferential evolution systems of mixed type with the measure of noncompactness

Results in Nonlinear Analysis, 2020
We consider the controllability problem for a class of fractional impulsive evolution systems of mixed type in an infinite dimensional Banach space. The existence of mild solutions and controllability results are discussed by a new estimation technique

Existence of solutions for some classes of integro-differential equations via measure of noncompactness

Electronic Journal of Qualitative Theory of Differential Equations, 2015
In this present paper, we introduce a new measure of noncompactness on the space consisting of all real functions which are $n$ times bounded and continuously differentiable on $\mathbb{R}_+$.

Existence of Weak Solutions for Fractional Integrodifferential Equations with Multipoint Boundary Conditions

International Journal of Differential Equations, 2018
By combining the techniques of fractional calculus with measure of weak noncompactness and fixed point theorem, we establish the existence of weak solutions of multipoint boundary value problem for fractional integrodifferential equations.

Existence Results for an Impulsive Neutral Fractional Integrodifferential Equation with Infinite Delay

International Journal of Differential Equations, 2014
We consider an impulsive neutral fractional integrodifferential equation with infinite delay in an arbitrary Banach space X. The existence of mild solution is established by using solution operator and Hausdorff measure of noncompactness.

Cauchy problems for functional evolution inclusions involving accretive operators

Electronic Journal of Qualitative Theory of Differential Equations, 2013
We study the existence and stability of solutions for a class of nonlinear functional evolution inclusions involving accretive operators. Our approach is employing the fixed point theory for multivalued maps and using estimates via the Hausdorff measure ...
