Hausdorff measure of noncompactness of certain matrix operators on absolute norlund spaces

, 2021
The absolute Norlund spaces vertical bar N-p(u)vertical bar(k), k >= 1, have more recently been introduced and studied by Hazar and Sargol [On absolute Norlund spaces and matrix operators, Acta Math. Sin. (Engl. Ser.), 34 (5) (2018), 812-826].

Fixed points of the Barnsley-Hutchinson operators induced by hyper-condensing maps

Le Matematiche, 2005
The aim of this note is to show that the Barnsley-Hutchinson operator, induced by either single h-bounded hyper-condensing map or a compact infinite family of such maps, admits a maximal fixed point and global attractor.Under suitable continuity ...

Remarks on a measure of weak noncompactness in the Lebesgue space

, 1995
Using the concept of equi-integrability we introduce a measure of weak noncompactness in the Lebesgue space L 1 (0, l).

Existence theorems for differential inclusions with nonconvex right hand side

International Journal of Mathematics and Mathematical Sciences, 1986
In this paper we prove some new existence theorems for differential inclusions with a nonconvex right hand side, which is lower semicontinuous or continuous in the state variable, measurable in the time variable and takes values in a finite or infinite ...

Quasilinear nonlocal integrodifferential equations in Banach spaces

Electronic Journal of Differential Equations, 2008
In this paper, we study the existence of mild solutions for quasilinear integrodifferential equations with nonlocal conditions in Banach spaces. The results are established by using Hausdorff's measure of noncompactness.

Dynamical behaviors of fractional neutral stochastic integro-differential delay systems with impulses

Boundary Value Problems
The aim of this manuscript is to analyze the stability for fractional neutral stochastic integro-differential delay systems (FNSIDDSs) with impulses driven by Poisson jumps.

New discussion on trajectory controllability of time-variant impulsive neutral stochastic functional integrodifferential equations via noncompact semigroup

Results in Applied Mathematics
The purpose of this paper is to determine a new discussion on trajectory-(T) controllability of time variant impulsive neutral stochastic functional integrodifferential equations (INSFIDEs) driven by fractional Brownian motion (fBm) via noncompact ...

Cauchy’s problem and measure of noncompactness

, 2023
In This Work, we study the notion the measure of noncompactness and we applied to the fractional differential equations on the goal to proof the existence of solution using fixed point theory combined with the Kuratouskii measure of ...
