### Existence of Almost Free Abelian groups and reflection of stationary set

by Shelah. [Sh:523]

Math Japonica, 1997

section 2: We answer a question of Mekler Eklof on the closure
operations of the incompactness spectrum. We answer a question
of Foreman and Magidor on reflection of stationary subsets of
S_{< aleph_2}(lambda) = {a subseteq lambda : |a| <
aleph_2}]. section 3 - NPT is not transitive. We prove
NPT(lambda, mu) + NPT(mu, kappa) not =>
NPT(lambda, kappa)
