Freely indecomposable almost free groups with free abelianization
Abstract
For certain uncountable cardinals $κ$ we produce a group of cardinality $κ$ which is freely indecomposable, strongly $κ$-free, and whose abelianization is free abelian of rank $κ$. The construction takes place in Gödel's constructible universe $L$. This strengthens an earlier result of Eklof and Mekler.
