Examples of asymptotically \ell_^1 Banach spaces

Abstract

Two examples of asymptotic 1\ell_{1} Banach spaces are given. The first, XuX_{u}, has an unconditional basis and is arbitrarily distortable. The second, XX, does not contain any unconditional basic sequence. Both are spaces of the type of Tsirelson. We thus answer a question raised by W.T.Gowers.
