Forcing with propositional Lindenbaum algebras.
σ-Entangled linear orders and narrowness of products of Boolean algebras
Saharon Shelah (1997)
Fundamenta Mathematicae
Similarity:
We investigate σ-entangled linear orders and narrowness of Boolean algebras. We show existence of σ-entangled linear orders in many cardinals, and we build Boolean algebras with neither large chains nor large pies. We study the behavior of these notions in ultraproducts.
Possibly every real function is continuous on a non-meagre set.

On Monk’s questions
Saharon Shelah (1996)
Fundamenta Mathematicae
Similarity:
We deal with Boolean algebras and their cardinal functions: π-weight π and π-character πχ. We investigate the spectrum of π-weights of subalgebras of a Boolean algebra B. Next we show that the π-character of an ultraproduct of Boolean algebras may be different from the ultraproduct of the π-characters of the factors.
