Ultracompanions of subsets of a group

I. Protasov, S. Slobodianiuk (2014)

Commentationes Mathematicae Universitatis Carolinae

Let $G$ be a group, $β G$ be the Stone-Čech compactification of $G$ endowed with the structure of a right topological semigroup and $G^{*} = β G ∖ G$ . Given any subset $A$ of $G$ and $p \in G^{*}$ , we define the $p$ -companion $Δ_{p} (A) = A^{*} \cap G p$ of $A$ , and characterize the subsets with finite and discrete ultracompanions.
