On a class of locally Butler groups

Ladislav Bican (1991)

Commentationes Mathematicae Universitatis Carolinae

A torsionfree abelian group $B$ is called a Butler group if $B e x t (B, T) = 0$ for any torsion group $T$ . It has been shown in [DHR] that under $C H$ any countable pure subgroup of a Butler group of cardinality not exceeding $ℵ_{ω}$ is again Butler. The purpose of this note is to show that this property has any Butler group which can be expressed as a smooth union $\cup_{α < μ} B_{α}$ of pure subgroups $B_{α}$ having countable typesets.
