On characterized subgroups of Abelian topological groups $X$ and the group of all $X$ -valued null sequences

S. S. Gabriyelyan (2014)

Commentationes Mathematicae Universitatis Carolinae

Let $X$ be an Abelian topological group. A subgroup $H$ of $X$ is characterized if there is a sequence $𝐮 = {u_{n}}$ in the dual group of $X$ such that $H = {x \in X : (u_{n}, x) \to 1}$ . We reduce the study of characterized subgroups of $X$ to the study of characterized subgroups of compact metrizable Abelian groups. Let $c_{0} (X)$ be the group of all $X$ -valued null sequences and $𝔲_{0}$ be the uniform topology on $c_{0} (X)$ . If $X$ is compact we prove that $c_{0} (X)$ is a characterized subgroup of $X^{ℕ}$ if and only if $X ≅ 𝕋^{n} \times F$ , where $n \geq 0$ and $F$ is a finite Abelian group. For every compact Abelian...
