  • Drinfeld Doubles for Finite Subgroups of SU(2) and SU(3) Lie Groups 
    Coquereaux, R.; Zuber, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    Drinfeld doubles of finite subgroups of SU(2) and SU(3) are investigated in detail. Their modular data – S, T and fusion matrices – are computed explicitly, and illustrated by means of fusion graphs. This allows us to ...
  • Drinfeld J Presentation of Twisted Yangians 
    Belliard, S.; Regelskis, V. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We present a quantization of a Lie coideal structure for twisted half-loop algebras of finite-dimensional simple complex Lie algebras. We obtain algebra closure relations of twisted Yangians in Drinfeld J presentation for ...
  • Duality-Symmetric Approach to General Relativity and Supergravity 
    Nurmagambetov, A.J. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    We review the application of a duality-symmetric approach to gravity and supergravity with emphasizing benefits and disadvantages of the formulation. Contents of these notes includes: 1) Introduction with putting the accent ...
  • Dunkl Hyperbolic Equations 
    Mejjaoli, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We introduce and study the Dunkl symmetric systems. We prove the well-posedness results for the Cauchy problem for these systems. Eventually we describe the finite speed of it. Next the semi-linear Dunkl-wave equations are ...
  • Dunkl Operators and Canonical Invariants of Reflection Groups 
    Berenstein, A.; Burman, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    Using Dunkl operators, we introduce a continuous family of canonical invariants of finite reflection groups. We verify that the elementary canonical invariants of the symmetric group are deformations of the elementary ...
  • Dunkl Operators as Covariant Derivatives in a Quantum Principal Bundle 
    Đurđevich, M.; Sontz, S.B. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    A quantum principal bundle is constructed for every Coxeter group acting on a finite-dimensional Euclidean space E, and then a connection is also defined on this bundle. The covariant derivatives associated to this connection ...
  • Dunkl-Type Operators with Projection Terms Associated to Orthogonal Subsystems in Root System 
    Bouzeffour, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    In this paper, we introduce a new differential-difference operator Tξ (ξ∈RN) by using projections associated to orthogonal subsystems in root systems. Similarly to Dunkl theory, we show that these operators commute and we ...
  • Duration of stay inside an interval by the poisson process with a negative exponential component 
    Kadankova, T. (2006)
    Several two-boundary problems for the Poisson process with an exponential component are solved in the present article. The integral transforms of the joint distribution of the epoch of the first exit from the interval and ...
  • Dynamical approach for positive solutions of semilinear elliptic problems in unbounded domains 
    Berestycki, H.; Efendiev, M.; Zelik, S. (Нелинейные граничные задачи, 2004)
    We apply the trajectory dynamical systems approach to study the positive solutions of a semilinear elliptic problem in an unbounded domain tt. The existence of the global attractor for the trajectory dynamical system ...
  • Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring 
    Wehefritz-Kaufmann, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has Uq(SU(3)) symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent ...
  • Dynamical Equations, Invariants and Spectrum Generating Algebras of Mechanical Systems with Position-Dependent Mass 
    Sara Cruz y Cruz; Rosas-Ortiz, Oscar (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We analyze the dynamical equations obeyed by a classical system with position-dependent mass. It is shown that there is a non-conservative force quadratic in the velocity associated to the variable mass. We construct the ...
  • Dynamical R matrices of elliptic quantum groups and connection matrices for the q-KZ equations 
    Konno, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    For any affine Lie algebra g, we show that any finite dimensional representation of the universal dynamical R matrix R(λ) of the elliptic quantum group Bq,λ(g) coincides with a corresponding connection matrix for the ...
  • Dynamical Studies of Equations from the Gambier Family 
    Guha, P.; Ghose Choudhury, A.; Grammaticos, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We consider the hierarchy of higher-order Riccati equations and establish their connection with the Gambier equation. Moreover we investigate the relation of equations of the Gambier family to other nonlinear differential ...
  • Dynamical system approach to solving linear programming problems and applications in economic modelling

    A class of dynamycal systems on symplectic manifolds solving linear programming problems is described. The structure of orbit space is analyzed in the framework of the Marsden – Weinstein reduction scheme. Some examples ...

  • Dynamics of an Inverting Tippe Top 
    Rauch-Wojciechowski, S.; Rutstam, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The existing results about inversion of a tippe top (TT) establish stability of asymptotic solutions and prove inversion by using the LaSalle theorem. Dynamical behaviour of inverting solutions has only been explored ...

    Szaszkowski, Z. (Algebra and Discrete Mathematics, 2003)
    Criterion of embedding of finite groups into the automorphism groups of a homogenous rooted tree of a spherical index n is formulated. The sets of natural numbers which are the lengths of all orbits of finite groups ...

    DeVille, L.; Lerman, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We propose a precise definition of a continuous time dynamical system made up of interacting open subsystems. The interconnections of subsystems are coded by directed graphs. We prove that the appropriate maps of graphs ...

    Paul, E.; Ramis, J.P. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    In the present paper, we will first present briefly a general research program about the study of the ''natural dynamics'' on character varieties and wild character varieties. Afterwards, we will illustrate this program ...

    Rizk, M.M. (Український математичний журнал, 2001)
    For the case of Hermitian interpolation, we consider the approximation-iterative method introduced by Dzyadyk. We construct a practical algorithm.
