Constructing Boolean algebras for cardinal invariants
Saharon Shelah
We construct Boolean Algebras answering questions of Monk on cardinal invariants. The results are proved in ZFC (rather than giving consistency results). We deal with the existence…

Consistency of partition relation for cardinal in (lambda,2^lambda)
Saharon Shelah, Lee Stanley
We present a forcing for blowing up 2^lambda and making ``many positive polarized partition relations'' (in a sense made precise in (c) of our main theorem) hold in the interval [l…
