细长余挠自由群的无穷公理化
Infinitary Axiomatizability of Slender and Cotorsion-Free Groups
摘要：
在无限逻辑L_{infty,omega_1}和L_{infty,omega}中，细长和无余挠阿贝尔群类分别是可公理化的. Baer-Specker群Z^ω不是L_{infty,omega_1} -等价于细长群。
英文摘要：
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 Z^omega is not L_{infty,omega_1}-equivalent to a slender group.
