Measure of noncompactness of operators and matrices on the spaces c and c0 [PDF]
, 2006 In this note, using the Hausdorff measure of noncompactness, necessary and sufficient conditions are formulated for a linear operator and matrices between the spaces c and c0 to be compact.

Solvability of nonlinear integral equations of product type
Electronic Journal of Differential Equations, 2018 This article concerns nonlinear functional integral equations of product type. The first two equations set on a the positive half-axis encompass different classes of nonlinear integral equations and may involve the product of finitely many integral ...

ON KURATOWSKI MEASURE OF NONCOMPACTNESS IN R 2 WITH THE RIVER METRIC
, 2020 In this paper we onsider some properties of the Kuratowski measure of noncompatness on the space (R2 , d* ), where d* is river metric. We prove the existence of the α-minimal sets in the given space, but also the strict minimalizability of the Kuratowski
