Abstract:

The classes of slender and cotorsion-free abelian groups are axiomatizable in the infinitary logics L_{\infty\omega_1} and L_{\infty\omega} respectively. The Baer-Specker group {\mathbb Z}^\omega is not L_{\infty\omega_1}-equivalent to a slender group. - Current version: 2000-01-17_10 (7p) published version (7p)
