Equivalences between certain properties of weighted Lipschitz operators

Functional Analysis 2026-03-25 v2

Abstract

We show that for a weighted Lipschitz operator ωf^\omega\widehat{f}, certain linear properties are equivalent. Specifically, we prove that compactness, strict singularity, and strict cosingularity are all equivalent to the property of not fixing any complemented copy of 1\ell^1. Then we generalize this result to operators between Lipschitz-free spaces that preserve finitely supported elements, a larger class of operators.
