 Title: Fragmentability of the Dual of a Banach Space with Smooth Bump Authors: Kortezov, I. Keywords: Smooth BumpFragmentabilitySigma-Fragmentability Issue Date: 1998 Publisher: Institute of Mathematics and Informatics Bulgarian Academy of Sciences Citation: Serdica Mathematical Journal, Vol. 24, No 2, (1998), 187p-198p Abstract: We prove that if a Banach space X admits a Lipschitz β-smooth bump function, then (X ∗ , weak ∗ ) is fragmented by a metric, generating a topology, which is stronger than the τβ -topology. We also use this to prove that if X ∗ admits a Lipschitz Gateaux-smooth bump function, then X is sigma-fragmentable.
