  • Densities, submeasures and partitions of groups 
    Banakh, T.; Protasov, I.; Slobodianiuk, S. (Algebra and Discrete Mathematics, 2014)
    In 1995 in Kourovka notebook the second author asked the following problem: is it true that for each partition G=A₁ ∪ ⋯ ∪ An of a group G there is a cell Ai of the partition such that G = FAiA⁻¹i for some set F ⊂ G of ...
  • On the subset combinatorics of G-spaces 
    Protasov, I.; Slobodianiuk, S. (Algebra and Discrete Mathematics, 2014)
    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 subsets of X, introduce and apply the relative combinatorical ...
  • Prethick subsets in partitions of groups 
    Protasov, I.V.; Slobodianiuk, S. (Algebra and Discrete Mathematics, 2012)
    A subset S of a group G is called thick if, for any finite subset F of G, there exists g ∈ G such that Fg ⊆ S, and k-prethick, k ∈ N if there exists a subset K of G such that |K| = k and KS is thick. For every finite ...
