  • Local Quasitriangular Hopf Algebras 
    Zhang, S.; Gould, M.D.; Zhang, Yao-Zhong (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We find a new class of Hopf algebras, local quasitriangular Hopf algebras, which generalize quasitriangular Hopf algebras. Using these Hopf algebras, we obtain solutions of the Yang-Baxter equation in a systematic way. The ...
  • Local solvability of fully nonlinear parabolic problems of higher order 
    Romanenko, I.B. (Нелинейные граничные задачи, 2000)
    The paper is devoted to reduction of fully nonlinear parabolic problems of high order to operator equations involving operator satisfying (S₊) condition. The topological methods could be used to investigate solvability of ...
  • Local sub-estimates of solutions to double phase parabolic equations via nonlinear parabolic potentials 
    Buryachenko, K.O. (Український математичний вісник, 2019)
    For parabolic equations with nonstandard growth conditions, we prove local boundedness of weak solutions in terms of nonlinear parabolic potentials of the right-hand side of the equation.
  • Local time as an element of the Sobolev space 
    Rudenko, A.V. (2007)
    For a centered Gaussian random ?eld taking its values in R^d, we investigate the existence of a local time as a generalized functional, i.e an element of some Sobolev space. We give the sfficient condition for such an ...
  • Long-range order in Gibbs lattice classical linear oscillator systems 
    Skrypnik, W.I. (Український математичний журнал, 2006)
    The existence of the ferromagnetic long-range order (lro) is proved for Gibbs classical lattice systems of linear oscillators interacting via a strong polynomial pair nearest neighbor (n-n) ferromagnetic potential and other ...
  • Long-range order in linear ferromagnetic oscillator systems. Strong pair quadratic n-n potential 
    Skrypnik, W.I. (Український математичний журнал, 2004)
    Long-range order is proved to exist for lattice linear oscillator systems with ferromagnetic potential energy containing a term with strong nearest-neighbor (n-n) quadratic pair potential. A contour bound and a generalized ...
  • Long-range order in quantum lattice systems of linear oscillators 
    Skrypnik, W.I. (Український математичний журнал, 2006)
    The existence of the ferromagnetic long-range order is proved for equilibrium quantum lattice systems of linear oscillators whose potential energy contains a strong ferromagnetic nearest-neighbor (nn) pair interaction term ...
  • Long-term returns in stochastic interest rate models 
    Zubchenko, V. (2007)
    We consider the behavior of integral functional of the solution of stochastic differential equation with coefficients contained small parameter. The dependence on the order of small parameter in every term of equation with ...
  • Long-Time Asymptotics for the Defocusing Integrable Discrete Nonlinear Schrödinger Equation II 
    Yamane, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We investigate the long-time asymptotics for the defocusing integrable discrete nonlinear Schrödinger equation. If |n| < 2t, we have decaying oscillation of order O(t⁻¹/²) as was proved in our previous paper. Near |n|=2t, ...
  • Long-Time Behavior of Nonautonomous Fokker-Planck Equations and Cooling of Granular Gases 
    Lods, B.; Toscani, G. (Український математичний журнал, 2005)
    We analyze the asymptotic behavior of linear Fokker-Planck equations with time-dependent coefficients. Relaxation towards a Maxwellian distribution with time-dependent temperature is shown under explicitly computable ...
  • Loop Quantum Gravity Phenomenology: Linking Loops to Observational Physics 
    Girelli, F.; Hinterleitner, F.; Major, S.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    Research during the last decade demonstrates that effects originating on the Planck scale are currently being tested in multiple observational contexts. In this review we discuss quantum gravity phenomenological models and ...
  • Loop Quantum Gravity Vacuum with Nondegenerate Geometry 
    Koslowski, T.; Sahlmann, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry. While this vacuum is singled out as fundamental due to its ...
  • Loops in SU(2), Riemann Surfaces, and Factorization, I 
    Basor, E.; Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In previous work we showed that a loop g:S¹→SU(2) has a triangular factorization if and only if the loop g has a root subgroup factorization. In this paper we present generalizations in which the unit disk and its double, ...
  • Lowest Weight Representations, Singular Vectors and Invariant Equations for a Class of Conformal Galilei Algebras 
    Aizawa, N.; Chandrashekar, R.; Segar, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    The conformal Galilei algebra (CGA) is a non-semisimple Lie algebra labelled by two parameters d and ℓ. The aim of the present work is to investigate the lowest weight representations of CGA with d=1 for any integer value ...

    Scarpetta, E.; Sumbatyan, M.A. (Нелінійні коливання, 2003)
    In the context of wave propagation through gratings of periodically distributed obstacles, we use analytical approaches to derive explicit formulas for the scattering parameters in the low-frequency approximation. The ...
