On the subset Combinatorics of G-spaces

Igor Protasov, Sergii Slobodianiuk

Let $G$ be a group and let $X$ be a transitive $G$ -space. We classify the subsets of $X$ with respect to a translation invariant ideal $J$ in the Boolean algebra of all s…

A conjecture on partitions of groups

Igor Protasov, Sergii Slobodianiuk

We conjecture that every infinite group $G$ can be partitioned into countably many cells $G = ⋃_{n \in ω} A_{n}$ such that $co v (A_{n} A_{n}^{- 1}) = ∣ G ∣$ for each $n \in ω$ . Here $cov(A)=\min…

A note on partitions of groups

Igor Protasov, Sergii Slobodianiuk

Every infinite group $G$ of regular cardinality can be partitioned $G = A_{1} \cup A_{2}$ so that $G \neq = F A_{1}$ , $G \neq = F A_{2}$ for every subset $F \subset G$ of cardinality $∣ F ∣ < ∣ G ∣$ . The fi…
