Thom, Andreas
Convergent Sequences in Discrete Groups
We prove that a finitely generated group contains a sequence of non-trivial elements that converge to the identity in every compact homomorphic image if and only if the group is not virtually abelian. As a consequence of the methods used, we show that a finitely generated group satisfies Chu duality if and only if it is virtually abelian.

Keywords:Chu duality, Bohr topology
Category:54H11
