Abstract
An abelian group is said to be ℵ1-free if all its countable subgroups are free. A crucial special case of our main result can be stated immediately.
Part of the work for this paper was carried out while the first author visited Rutgers University. He would like to thank the organizers of MAMLS and the Department of Mathematics for their support.
Number of publication 519. Research was supported by the Edmund Landau Center for research in Mathematical Analysis, supported by the Minerva Foundation (Germany)
