摘要:

The theory of torsion-free abelian groups is developed, in a manner that is constructive in the sense of Bishop, up to the fundamental the orem that, for finite-rank completely decomposable torsion-free groups, the class of finite-rank pure subgroups is coextensive with the class of finite-rank torsion-free quotients.
