Differentiability of Banach Spaces via Constructible Sets

Functional Analysis 2009-01-31 v2

Abstract

the main goal of this paper is to prove that any Banach space X, that every dual ball in X** is weak* -separable, or every weak* -closed convex subset in X** is weak* -separable, or every norm-closed convex set in X* is constructible, admits an equivalent Frechet differentiable norm.
