### On densities of box products

by Gitik and Shelah. [GiSh:597]

Topology and its Applications, 1998

We construct two universes V_1, V_2 satisfying the following:
GCH below aleph_omega, 2^{aleph_omega}= aleph_{omega +2} and
the topological density of the space {}^{aleph_omega} 2 with
aleph_0 box product topology d_{< aleph_1}(aleph_omega) is
aleph_{omega +1} in V_1 and aleph_{omega +2} in V_2 .
Further related results are discussed as well.
