The minimal displacement and extremal spaces

Functional Analysis 2015-11-24 v1

Abstract

We show that both separable preduals of L1L_{1} and non-type I CC^*-algebras are strictly extremal with respect to the minimal displacement of kk-Lipschitz mappings acting on the unit ball of a Banach space. In particular, every separable C(K)C(K) space is strictly extremal.
