The Szlenk index and local ?1-indices [PDF]

open access: yesPositivity, 2005
We introduce two new local l1-indices of the same type as the Bourgain l1-index; the l+1-index and the l+1-weakly null index. We show that the l+1-weakly null index of a Banach space X is the same as the Szlenk index of X, provided X does not contain l1.

Shift invariant preduals of ℓ1(ℤ) [PDF]

open access: yes, 2011
The Banach space ℓ<sub>1</sub>(ℤ) admits many non-isomorphic preduals, for example, C(K) for any compact countable space K, along with many more exotic Banach spaces.

Some strongly bounded classes of Banach spaces [PDF]

open access: yes, 2006
We show that the classes of separable reflexive Banach spaces and of spaces with separable dual are strongly bounded. This gives a new proof of a recent result of E. Odell and Th.

The Szlenk index of L p (X )

open access: yesBulletin of the London Mathematical Society, 2014
We find an optimal upper bound on the values of the weak$^*$-dentability index $Dz(X)$ in terms of the Szlenk index $Sz(X)$ of a Banach space $X$ with separable dual. Namely, if $\;Sz(X)= ^ $, for some $

Operators on two Banach spaces of continuous functions on locally compact spaces of ordinals [PDF]

open access: yes, 2015
Denote by $[0,\omega_1)$ the set of countable ordinals, equipped with the order topology, let $L_0$ be the disjoint union of the compact ordinal intervals $[0,\alpha]$ for $\alpha$ countable, and consider the Banach spaces $C_0[0,\omega_1)$ and $C_0(L_0)$

The Szlenk index of Orlicz sequence spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 2010
Summary: We provide explicit estimates of the Szlenk indices of Orlicz sequence spaces. Applications are given to uniform homeomorphisms between subspaces and quotients of Orlicz spaces.

Concerning the Szlenk index

open access: yesStudia Mathematica, 2017
We discuss pruning and coloring lemmas on regular families. We discuss several applications of these lemmas to computing the Szlenk index of certain $w^*$ compact subsets of the dual of a separable Banach space. Applications include estimates of the Szlenk index of Minkowski sums, infinite direct sums of separable Banach spaces, constant reduction, and
