Precipitousness of a Sum of Ideals on Complete Boolean Algebras

Mathematical Logic Quarterly, 1988
\textit{T. Jech} and \textit{K. Prikry} [Mem. Am. Math. Soc. 214 (1979; Zbl 0398.03044)] introduced the notion of precipitousness for ideals on power set algebras. This notion is closely connected with well-foundedness of generic ultrapowers of models of set theory.

Dense subtrees in complete Boolean algebras

Mathematical Logic Quarterly, 2006
AbstractWe characterize complete Boolean algebras with dense subtrees. The main results show that a complete Boolean algebra contains a dense tree if its generic filter collapses the algebra's density to its distributivity number and the reverse holds for homogeneous algebras.
