On a measure of non–compactness for maximal operators

Mathematische Nachrichten, 2003
AbstractIt is proved that there is no weight pair (v,w) for which the Hardy–Littlewood maximal operator defined on a domain Ω in Rn is compact from the weighted Lebesgue space Lpw(Ω) to Lpv (Ω). Results of a similar character are also obtained for the fractional maximal operators.

Measures of Non-Compactness and Sobolev–Lorentz Spaces

Zeitschrift für Analysis und ihre Anwendungen, 2020
We show that the measure of non-compactness of the limiting embedding of Sobolev–Lorentz spaces is equal to the norm. This is a consequence of our general theorem for arbitrary Banach spaces.

Measures of Non-compactness

2014
The degree of non-compactness of a set is measured by means of functions called measures of non-compactness. In this chapter we study the three main and most frequently used measures of non-compactness (MNCs).

KURATOWSKI'S MEASURE OF NON-COMPACTNESS REVISITED

The Quarterly Journal of Mathematics, 1988
The author earlier introduced the category of approach spaces with contractions, which contains the topological spaces with continuous maps as a bireflective and bicoreflective subcategory and the extended pseudo- quasi-metric spaces with non-expansive maps as a bicoreflective subcategory. A measure of non-compactness is defined for approach spaces and
