Abstract
Motivated by an application to the unconditional basic sequence problem appearing in our previous paper, we introduce analogues of the Laver ideal on N 2 living on index sets of the form [N k] ω and use this to refine the well-known high-dimensional polarized partition relation for N ω of Shelah. © Instytut Matematyczny PAN, 2012.
