Compactification, and beyond, of composition operators on Hardy spaces by weights

Functional Analysis 2019-04-16 v1

Abstract

We study when multiplication by a weight can turn a non-compact composition operator on H 2 into a compact operator, and when it can be in Schatten classes. The q-summing case in H p is considered. We also study when this multiplication can turn a compact composition operator into a non-compact one. MSC 2010 primary: 47B33 ; secondary: 46B28
