Title: Uncountable abelian groups that want to be free
Abstract: The title refers to those abelian groups whose failure to be free is caused by settheoretic rather than algebraic issues. An easy example is the group of infinite sequences of integers (with the operation of componentwise addition). I plan to use the theory of such groups, in particular questions about how far they are from being free, as a motivation for giving quick glimpses of some of the main areas of contemporary set theory.
