Information pasts in groups
A. V. Safonov
Abstract:
A simple algebraic characterization is obtained for information pasts in amenable groups. It is proved that a subset $P$ of a countable amenable group $G$ is an information past in $G$ if and only if the set of negative elements for some linear ordering of $G$ is invariant under left translations.
