  • On disjoint union of M-graphs 
    Kozerenko, S. (Algebra and Discrete Mathematics, 2017)
    Given a pair (X,σ) consisting of a finite tree X and its vertex self-map σ one can construct the corresponding Markov graph Γ(X,σ) which is a digraph that encodes σ-covering relation between edges in X. M-graphs are Markov ...
  • On graphs with graphic imbalance sequences 
    Kozerenko, S.; Skochko, V. (Algebra and Discrete Mathematics, 2014)
    The imbalance of the edge e = uv in a graph G is the value imbG(e) = |dG(u) − dG(v)|. We prove that the sequence MG of all edge imbalances in G is graphic for several classes of graphs including trees, graphs in which all ...
  • On Markov graphs 
    Kozerenko, S. (Algebra and Discrete Mathematics, 2013)
    We investigate graph-theoretical properties of Markov graphs from dynamical systems.
