Kulikov's problem on universal torsion-free abelian groups revisited
收藏 引用
BULLETIN OF THE LONDON MATHEMATICAL SOCIETY 2011年 第6期43卷 1198-1204页
作者: Shelah, Saharon Struengmann, Lutz Hebrew Univ Jerusalem Dept Math IL-91904 Jerusalem Israel Rutgers State Univ Piscataway NJ 08854 USA Univ Duisburg Essen Fac Math D-45117 Essen Germany
Let T be a torsion abelian group. We consider the class of all torsion-free abelian groups G satisfying Ext(G, T) = 0 and search for lambda-universal objects in this class. We show that, for certain T, there is no ome... 详细信息
