  • Non-Local Finite-Size Effects in the Dimer Model 
    Izmailian, N.Sh.; Priezzhev, V.B.; Ruelle, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We study the finite-size corrections of the dimer model on ∞ × N square lattice with two different boundary conditions: free and periodic. We find that the finite-size corrections depend in a crucial way on the parity of ...

    We have constructed new formulae for generation of solutions for the nonlinear heat equation and for the Burgers equation that are based on linearizing nonlocal transformations and on nonlocal symmetries of linear equations. ...
  • Nonlocal Symmetries, Telescopic Vector Fields and λ-Symmetries of Ordinary Differential Equations 
    Muriel, C.; Romero, J.L. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    This paper studies relationships between the order reductions of ordinary differential equations derived by the existence of λ-symmetries, telescopic vector fields and some nonlocal symmetries obtained by embedding the ...
  • Nonlunear resonant tunnelling through doubly degenerate local state and strong electron-phonon interaction 
    Ermakov, V.N. (Физика низких температур, 1999)
    In an approach of low transparency of the barrier the tunneling of electrons through doubly degenerate local state has been considered with allowance for the Coulomb and electron-phonon interactions. It is shown that in ...
  • Non-Markovian effects in turbulent diffusion: kinetic theory and numerical simulation 
    Zagorodny, A.G.; Zasenko, V.I.; Weiland, J.; Holod, I. (Вопросы атомной науки и техники, 2002)
    The theory of time-nonlocal random processes formulated in terms of non-Markovian Fokker-Planck equation is used to describe the results of numerical simulations of particle diffusion in the random longitudinal field with ...
