Based on a construction method introduced by J. Bourgain and F. Delbaen, we give a general definition of a Bourgain-Delbaen space and prove that every infinite dimensional separableExpand
Operators on Bourgain–Delbaen spaces
We prove that, for a suitable choice of real numbers $a, b$, every operator from $\ell_2$ to $X_{a,b}$ and from $X_{a,b}$ to $\ell_2$ must be compact, where $X_{a,b}$ is the Bourgain- Delbaen's space.
An unconditionally saturated Banach space with the scalar-plus-compact property
Abstract We construct a Bourgain–Delbaen L ∞ -space X K u s with structure that is strongly heterogeneous: any bounded operator on X K u s is a compact perturbation of a multiple of the identity,Expand

On the undefinability of Tsirelson's space and its descendants.
