Homomorphic encoders of profinite abelian groups I

María V. Ferrer, Salvador Hernández

Let ${G_{i} : i \in N}$ be a family of finite Abelian groups. We say that a subgroup $G \leq i \in N \prod G_{i}$ is \emph{order controllable} if for every $i \in N$ the…

On the structure of abelian profinite groups

María V. Ferrer, Salvador Hernández

A subgroup $G$ of a product $i \in N \prod G_{i}$ is \emph{rectangular} if there are subgroups $H_{i}$ of $G_{i}$ such that $G = i \in N \prod H_{i}$ . We say th…
