چکیده
We show that the classification problem for genus n Banach spaces can be reduced to the unconditionally primary case and that the critical case there is n = 2. It is further shown that a genus n Banach space is unconditionally primary if and only if it contains a complemented subspace of genus (n − 1). We begin the process of classifying the genus 2 spaces by showing they have a strong decomposition property.

New concepts related to approximating a Lipschitz function between Banach spaces by affine functions are introduced. Results which clarify when such approximations are possible are proved and in some cases a complete characterization of the spaces X, Y for which any Lipschitz function from X to Y can be so approximated is obtained. This is applied to the study of Lipschitz and uniform quotient ...

A bounded linear operator between Banach spaces is called completely continuous if it carries weakly convergent sequences into norm convergent sequences. Isolated is a universal operator for the class of non-completely-continuous operators from L1 into an arbitrary Banach space, namely, the operator from L1 into l∞ defined by

Any regular mixed Tsirelson space T (θ n , S n) I N for which θn θ n → 0, where θ = lim n θ 1/n n , is shown to be arbitrarily distortable. Certain asymptotic ℓ 1 constants for those and other mixed Tsirelson spaces are calculated. Also a combinatorial result on the Schreier families (S α) α<ω 1 is proved and an application is given to show that for every Banach space X with a basis (e i), the ...

The main object of the paper is to study the distance between Banach spaces introduced by Kadets. For Banach spaces X and Y , the Kadets distance is defined to be the infimum of the Hausdorff distance d(B X , B Y) between the respective closed unit balls over all isometric linear embeddings of X and Y into a common Banach space Z. This is compared with the Gromov-Hausdorff distance which is def...
