  • On classification of groups generated by 3-state automata over a 2-letter alphabet 
    Bondarenko, I.; Grigorchuk, R.; Kravchenko, R.; Muntyan, Y.; Nekrashevych, V.; Savchuk, D.; Sunic, Z. (Algebra and Discrete Mathematics, 2008)
    We show that the class of groups generated by 3-state automata over a 2-letter alphabet has no more than 122 members. For each group in the class we provide some basic information, such as short relators, a few initial ...
  • Role of turbulence and electric fields in the formation of transport barriers and the establishment of improved confinement in tokamak plasmas through inter-machine comparison 
    Van Oost, G.; Bulanin, V.; Donné, A.J.H.; Gusakov, E.; Krämer-Flecken, A.; Krupnik, L.; Heikkinen, J.; Melnikov, A.; Razumova, K.; Rozhansky, V.; Stöcke, J.; Tendler, M.; Van Schoor, M.; Vershkov, V.; Zajac, J.; Altukov, A.; Andreev, V.; Askinazi, L.; Bondarenko, I.; Dnestrovskij, A.; Eliseev, L.; Esipov, L.; Grashin, S.; Gurchenko, A.; Hogeweij, G.M.D.; Kantor, M.; Kaveeva, E.; Kiviniemi, T.; Khrebtov, S.; Kouprienko, D.; Kurki-Suonio, T.; Lashkul, S.; Lebedev, S.; Leerink, S.; Lysenko, S.; Ogando, F.; Perfilov, S.; Petrov, A.; Popov, A.; Shelukhin, D.; Shurygin, R.; Soldatov, S.; Stepanov, A.; Xu, Y. (Вопросы атомной науки и техники, 2009)
    Over the past decade new regimes of tokamak operation have been identified, whereby electrostatic and magnetic turbulence responsible for anomalous transport, can be externally suppressed, leading to improved confinement. ...
  • Schreier Graphs for a Self-Similar Action of the Heisenberg Group 
    Bondarenko, I.; Kravchenko, R. (Український математичний журнал, 2013)
    We construct a faithful self-similar action of the discrete Heisenberg group with the following properties: This action is self-replicating, finite-state, level-transitive, and noncontracting. Moreover, there exist orbital ...
  • The word problem in Hanoi Towers groups 
    Bondarenko, I. (Algebra and Discrete Mathematics, 2014)
    We prove that the elements of the Hanoi Towers groups Hm have depth bounded from above by a poly-logarithmic function O(logm⁻²n), where n is the length of an element. Therefore the word problem in groups Hm is solvable in ...
