On a measure of noncompactness in the space of regulated functions and its applications

open access: yes, 2018
In this paper we formulate a criterion for relative compactness in the space of functions regulated on a bounded and closed interval. We prove that the mentioned criterion is equivalent to a known criterion obtained earlier by D.

On the Construction of a Norm Associated with the Measure of Noncompactness [PDF]

open access: yes, 1976
It is shown that the bounded, nonempty subsets of a reflexive Banach space g can be imbedded in another Banach space B(E) in such a manner so that the measure of noncompactness corresponds to the norm in B(E).

Advances in Nonlinear Analysis via the Concept of Measure of Noncompactness

open access: yes, 2017
This book offers a comprehensive treatment of the theory of measures of noncompactness. It discusses various applications of the theory of measures of noncompactness, in particular, by addressing the results and methods of fixed-point theory. The concept
