A matrix subadditivity inequality for symmetric norms

jean-Christophe Bourin

Well-known subadditivity results for positive operators (of Brown-Kosaki and Rotfeld/Ando-Zhan types) are extended to Hermitian and normal ones. Applications to Cartesian decomposi…

$C^{k}$ -smooth approximations of LUR norms

Petr Hajek, Antonin Prochazka

Let $X$ be a WCG Banach space admitting a $C^{k}$ -Fr\' echet smooth norm. Then $X$ admits an equivalent norm which is simultaneously $C^{1}$ -Fr\' echet smooth, LUR, and a uniform limit…

Weak $^{*}$ dentability index of spaces $C ([0, α])$

Petr Hajek, Gilles Lancien, Antonin Prochazka

We compute the weak $^{*}$ -dentability index of the spaces $C (K)$ where $K$ is a countable compact space. Namely $D z (C ([0, ω^{ω^{α}}])) = ω^{1 + α + 1}$ , whenever $0 \leq α < ω_{1}$ . More general…
