Abstract

We show that, in some cases, the projective and the injective tensor products of two Banach spaces do not have the Dunford–Pettis property (DPP). As a consequence, we obtain that (c0 &[otimes B: multiply sign in circle]circ;π c0)** fails the DPP. Since (c0 &[otimes B: multiply sign in circle]circ;π c0)* does enjoy it, this provides a new space with the DPP whose dual fails to have it. We also prove that, if E and F are [script L]1-spaces, then E &[otimes B: multiply sign in circle]circ;ε has the DPP if and only if both E and F have the Schur property. Other results and examples are given.
