The Cohen algebra embeds as a
complete subalgebra into three classic families of complete, atomless, c.c.c.,
non-measur- able Boolean algebras; namely, the families of Argyros algebras and
Galvin-Hajnal algebras, and the atomless part of each Gaifman algebra. It
immediately follows that the weak (ω,ω)-distributive law fails everywhere in each of
these Boolean algebras.
