Generalized symmetric systems and thin-very tall compact scattered spaces

Abstract

We solve a well--known problem in the theory of compact scattered spaces and superatomic boolean algebras by showing that, under GCH and for each regular cardinal κω\kappa \geq \omega, there is a poset Pκ\mathcal P_\kappa preserving all cardinals and forcing the existence of a κ\kappa--thin very tall locally compact scattered space. For κ>ω\kappa > \omega, we conceive the poset Pκ\mathcal P_\kappa as a higher analogue of the poset Pω\mathcal P_\omega originally introduced by Asper\'{o} and Bagaria in the context of an (unpublished) alternative consistency proof.
