  • Chalykh, O. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We consider one-dimensional elliptic Ruijsenaars model of type BC₁. It is given by a three-term difference Schrödinger operator L containing 8 coupling constants. We show that when all coupling constants are integers, L ...
  • Kuniba, A.; Takagi, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We study an integrable vertex model with a periodic boundary condition associated with Uq(An⁽¹⁾ at the crystallizing point q=0. It is an (n+1)-state cellular automaton describing the factorized scattering of solitons. The ...
  • Links, J.; Hibberd, K.E. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    The Bose-Hubbard dimer Hamiltonian is a simple yet effective model for describing tunneling phenomena of Bose-Einstein condensates. One of the significant mathematical properties of the model is that it can be exactly ...
  • Sasaki, Ryu; Yang, Wen-Li; Zhang, Yao-Zhong (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    Bethe ansatz formulation is presented for several explicit examples of quasi exactly solvable difference equations of one degree of freedom which are introduced recently by one of the present authors. These equations are ...
  • Karimou, M.; Yessoufou, R.A.; Oke, T.D.; Kpadonou, A.; Hontinfinde, F. (Condensed Matter Physics, 2016)
    The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic field h via the recursion relations method. A ground-state phase diagram is constructed which may be needful to ...
  • Eddahri, S.; Karimou, M.; Razouk, A.; Hontinfinde, F.; Benyoussef, A. (Condensed Matter Physics, 2018)
    The magnetic properties of the mixed spin- 1/2 and spin- 7/2 Ising model with a crystal-field in a longitudinal magnetic field are investigated on the Bethe lattice using exact recursion relations. The ground-state phase ...
  • Fuksa, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    Supersymmetric composite generalized quantum integrable models solvable by the algebraic Bethe ansatz are studied. Using a coproduct in the bialgebra of monodromy matrix elements and their action on Bethe vectors, formulas ...
  • Belliard, S.; Pakuliak, S.; Ragoucy, E.; Slavnov, N.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We study quantum integrable models with GL(3) trigonometric R-matrix and solvable by the nested algebraic Bethe ansatz. Using the presentation of the universal Bethe vectors in terms of projections of products of the ...
  • Rozmainsky, I.V. (Економічний вісник Донбасу, 2013)
    The paper contains attempt to go beyond dualism between determinism and voluntarism in dynamic economics. On one hand, economic dynamics is not predetermined by tastes, endowments and technologies (as Neoclassical Economics ...
  • Ballesteros, A.; Garcia, G.; Bogede, L.; Bros, J. (Проблемы прочности, 2004)
    A set of standard reactor pressure vessels (RPV) surveillance programs for monitoring the design life (up to 40 years of reactor operation) have been analyzed. In view of the improved test methods and embrittlement ...
  • Fujii, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In this paper we present a non-Gaussian integral based on a cubic polynomial, instead of a quadratic, and give a fundamental formula in terms of its discriminant. It gives a mathematical reinforcement to the recent result ...
  • Inés García de la Puente (Ruthenica, 2022)
  • Калініченко, О.В.; Мишуніна, Т.М.; Тронько, М.Д. (Український біохімічний журнал, 2010)
    У плазмі крові хворих із різними захворюваннями щитовидної, паращитовидних та надниркових залоз досліджували В-, Н- та L-катепсиноподібну активність по відношенню до Nα-бензоїл-D,L-аргінін-4-нітроаніліду, L-лейцин-4-нітроаніліду ...
  • Grzybowski, J. (Сторінки воєнної історії України, 2011)
    У статті «Білоруський національний рух щодо українських прагнень незалежності в 1939–1956 рр.» встановлено особливості відносин між українськими та білоруськими національними силами в роки Другої світової війни і в ...
  • Sakhno, L. (2007)
    We consider estimators for integrals of a spectrum and a bispectrum for random fields X(t), t belongs R^d, and present conditions guaranteeing the rate of convergence of bias to zero appropriate for dimensions d = 1, 2, 3.
  • Trotsenko, O.G.; Babich, A.V.; Ostapchuk, P.M. (Problems of Atomic Science and Technology, 2023)
    Using the analytical expression for the energy of elastic interaction of radiation point defects with a prismatic edge dislocation loop of zirconium (Burgers vector bᴰ=1/3⟨1120⟩, {1120} occurrence plane), the bias of loops ...
  • Babich, A.V.; Ostapchuk, P.N. (Вопросы атомной науки и техники, 2021)
    An analytical expression for the elastic interaction energy of radiation point defects of the dipole type with the basal dislocation loop of the hcp metal is obtained using the Green's function method for hexagonal crystals ...
  • Karakuş, S.Ö.; Yayli, Y. (Український математичний журнал, 2012)
    We show that a hyperquadric M in R⁴₂ is a Lie group by using the bicomplex number product. For our purpose, we change the definition of tensor product. We define a new tensor product by considering the tensor product surface ...
  • Agore, A.L.; Militaru, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    For a perfect Lie algebra h we classify all Lie algebras containing h as a subalgebra of codimension 1. The automorphism groups of such Lie algebras are fully determined as subgroups of the semidirect product h⋉(k∗×AutLie(h)). ...

    We express AKNS hierarchies, admitting reductions to matrix NLS and matrix mKdV hierarchies, in terms of a bidifferential graded algebra. Application of a universal result in this framework quickly generates an infinite ...
