Rotund Gateaux smooth norms which are not locally uniformly rotund

Functional Analysis 2024-02-28 v2

Abstract

We provide, in every infinite-dimensional separable Banach space, an average locally uniformly rotund (and hence rotund) Gateaux smooth renorming which is not locally uniformly rotund. This solves an open problem posed by A.J. Guirao, V. Montesinos, and V. Zizler.
