  • Protasov, I.V.; Protasova, K.D. (Algebra and Discrete Mathematics, 2007)
    A regular connected graph Γ of degree s is called kaleidoscopical if there is a (s + 1)-coloring of the set of its vertices such that every unit ball in Γ has no distinct monochrome points. The kaleidoscopical graphs can ...
  • Protasov, I.V.; Protasova, K.D. (Algebra and Discrete Mathematics, 2017)
    We introduce and analyze the following general concept of recurrence. Let G be a group and let X be a G-space with the action G×X⟶X, (g,x)⟼gx. For a family F of subset of X and A∈F, we denote ΔF(A)={g∈G:gB⊆A for some B∈F, ...
  • Protasova, K.D. (Algebra and Discrete Mathematics, 2005)
    A finite connected graph G is called squareHamiltonian if G² is Hamiltonian. We prove that any join of the family of Hamiltonian graphs by tree is square-Hamiltonian. Applying this statement we show that the line graph ...
