  • On 2-state Mealy automata of polynomial growth 
    Reznykov, I.I. (Algebra and Discrete Mathematics, 2003)
    We consider the sequence of 2-state Mealy automata over the finite alphabets, that have polynomial growth orders and define the infinitely presented automatic transformation semigroups.
  • On faithful actions of groups and semigroups by orientation-preserving plane isometries 
    Vorobets, Y. (Algebra and Discrete Mathematics, 2003)
    Feitful representations of two generated free groups and free semigroups by orientation-preserving plane isometries constructed.
  • On subgroups of saturated or totally bounded paratopological groups 
    Banakh, T.; Ravsky, S. (Algebra and Discrete Mathematics, 2003)
    A paratopological group G is saturated if the inverse U ⁻¹ of each non-empty set U ⊂ G has non-empty interior. It is shown that a [first-countable] paratopological group H is a closed subgroup of a saturated (totally ...
  • Post-critically finite self-similar groups 
    Bondarenko, E.; Nekrashevych, V. (Algebra and Discrete Mathematics, 2003)
    We describe in terms of automata theory the automatic actions with post-critically finite limit space. We prove that these actions are precisely the actions by bounded automata and that any self-similar action by bounded ...
  • Structural properties of extremal asymmetric colorings 
    Verbitsky, O. (Algebra and Discrete Mathematics, 2003)
    Let Ω be a space with probability measure µ for which the notion of symmetry is defined. Given A ⊆ Ω, let ms(A) denote the supremum of µ(B) over symmetric B ⊆ A. An r-coloring of Ω is a measurable map χ : Ω → {1, . . . , ...
