Kadec norms on spaces of continuous functions

Abstract

We study the existence of pointwise Kadec renormings for Banach spaces of the form C(K)C(K). We show in particular that such a renorming exists when KK is any product of compact linearly ordered spaces, extending the result for a single factor due to Haydon, Jayne, Namioka and Rogers. We show that if C(K1)C(K_1) has a pointwise Kadec renorming and K2K_2 belongs to the class of spaces obtained by closing the class of compact metrizable spaces under inverse limits of transfinite continuous sequences of retractions, then C(K1×K2)C(K_1\times K_2) has a pointwise Kadec renorming. We also prove a version of the three-space property for such renormings.
