abstract
We prove that, when 2 < p < ∞, in the free Banach lattice generated by p (respectively by c0), the absolute values of the canonical basis form an r-sequence, where [...] (respectively an l2-sequence). In particular, in any Banach lattice, the absolute values of any p sequence always have an upper r-estimate. Quite surprisingly, this implies that the free Banach lattices generated by the nonseparable [...], are weakly compactly generated whereas this is not the case for 1 ≤ p ≤ 2.
