An ordinal index characterizing weak compactness of operators

Functional Analysis 2015-08-25 v3

Abstract

We introduce an ordinal index which characterizes weak compactness of operators between Banach spaces. We study when classes consisting of operators having bounded index form a closed ideal, the distinctness of the classes, and the descriptive set theoretic properties of this index.
