Résumé

We investigate the set (ω) of partitions of the natural numbers ordered by ≤^* where A ≤^* B if by gluing finitely many blocks of A we can get a partition coarser than B. In particular, we determine the values of a number of cardinals which are naturally associated with the structure ((ω),≥^*), in terms of classical cardinal invariants of the continuum.
