Characterized subgroups of topological abelian groups
Dikran Dikranjan, Anna Giordano Bruno, Daniele Impieri
A subgroup of a topological abelian group is said to be characterized by a sequence of characters of if $H=\{x\in X:v_n(x)\to 0\ \text{in}\ \mathbb T…

On the Borel Complexity of Characterized Subgroups
Dikran Dikranjan, Daniele Impieri
In a compact abelian group , a characterized subgroup is a subgroup such that there exists a sequence of characters $\vs=(v_n)$ of such that $H=\{x\in X:v_n(x)\to 0 \tex…

Questions on the Borel Complexity of Characterized Subgroups
Dikran Dikranjan, Daniele Impieri
We propose various problems about Borel complexity of characterized subgroups of compact abelian groups, inspired by our forthcoming paper \cite{DI3}.
