  • Rapidities and Observable 3-Velocities in the Flat Finslerian Event Space with Entirely Broken 3D Isotropy 
    Bogoslovsky, G.Yu. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We study the geometric phase transitions that accompany the dynamic rearrangement of vacuum under spontaneous violation of initial gauge symmetry. The rearrangement may give rise to condensates of three types, namely the ...
  • Recent Applications of the Theory of Lie Systems in Ermakov Systems 
    Cariñena, J.F.; de Lucas, J.; Rañada, M.F. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We review some recent results of the theory of Lie systems in order to apply such results to study Ermakov systems. The fundamental properties of Ermakov systems, i.e. their superposition rules, the Lewis-Ermakov invariants, ...
  • Reductions of Multicomponent mKdV Equations on Symmetric Spaces of DIII-Type 
    Gerdjikov, V.S.; Kostov, N.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    New reductions for the multicomponent modified Korteweg-de Vries (MMKdV) equations on the symmetric spaces of DIII-type are derived using the approach based on the reduction group introduced by A.V. Mikhailov. The relevant ...
  • Relative differential K-characters 
    Maghfoul, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We define a group of relative differential K-characters associated with a smooth map between two smooth compact manifolds. We show that this group fits into a short exact sequence as in the non-relative case. Some secondary ...
  • Riccati and Ermakov Equations in Time-Dependent and Time-Independent Quantum Systems 
    Schuch, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The time-evolution of the maximum and the width of exact analytic wave packet (WP) solutions of the time-dependent Schrödinger equation (SE) represents the particle and wave aspects, respectively, of the quantum system. ...
  • Schwinger-Fronsdal Theory of Abelian Tensor Gauge Fields 
    Guttenberg, S.; Savvidy, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    This review is devoted to the Schwinger and Fronsdal theory of Abelian tensor gauge fields. The theory describes the propagation of free massless gauge bosons of integer helicities and their interaction with external ...
  • Shoikhet's Conjecture and Duflo Isomorphism on (Co)Invariants 
    Calaque, D.; Rossi, C.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    In this paper we prove a conjecture of B. Shoikhet. This conjecture states that the tangent isomorphism on homology, between the Poisson homology associated to a Poisson structure on Rd and the Hochschild homology of its ...
  • Single-Pole Interaction of the Particle with the String 
    Vasilic, M.; Vojinovic, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    Within the framework of generalized Papapetrou method, we derive the effective equations of motion for a string with two particles attached to its ends, along with appropriate boundary conditions. The equations of motion ...
  • sl(2)-Trivial Deformations of VectPol(R)-Modules of Symbols 
    Ben Ammar, M.; Boujelbene, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We consider the action of VectPol(R) by Lie derivative on the spaces of symbols of differential operators. We study the deformations of this action that become trivial once restricted to sl(2). Necessary and sufficient ...
  • Solutions Classification to the Extended Reduced Ostrovsky Equation 
    Stepanyants, Y.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    An alternative to the Parkes' approach [SIGMA 4 (2008), 053, 17 pages] is suggested for the solutions categorization to the extended reduced Ostrovsky equation (the exROE in Parkes' terminology). The approach is based on ...
  • Solvable Two-Body Dirac Equation as a Potential Model of Light Mesons 
    Duviryak, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The two-body Dirac equation with general local potential is reduced to the pair of ordinary second-order differential equations for radial components of a wave function. The class of linear + Coulomb potentials with ...
  • Some Orthogonal Polynomials in Four Variables 
    Dunkl, C.F. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The symmetric group on 4 letters has the reflection group D₃ as an isomorphic image. This fact follows from the coincidence of the root systems A₃ and D₃. The isomorphism is used to construct an orthogonal basis of polynomials ...
  • Sonine Transform Associated to the Dunkl Kernel on the Real Line 
    Soltani, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We consider the Dunkl intertwining operator Vα and its dual tVα, we define and study the Dunkl Sonine operator and its dual on R. Next, we introduce complex powers of the Dunkl Laplacian Δα and establish inversion formulas ...
  • Space-Time Diffeomorphisms in Noncommutative Gauge Theories 
    Rosenbaum, M.; Vergara, J.D.; Juarez, L.R. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    In previous work [Rosenbaum M. et al., J. Phys. A: Math. Theor. 40 (2007), 10367–10382] we have shown how for canonical parametrized field theories, where space-time is placed on the same footing as the other fields in the ...
  • String Functions for Affine Lie Algebras Integrable Modules 
    Kulish, P.; Lyakhovsky, V. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
  • SUSY Quantum Hall Effect on Non-Anti-Commutative Geometry 
    Hasebe, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We review the recent developments of the SUSY quantum Hall effect [hep-th/0409230, hep-th/0411137, hep-th/0503162, hep-th/0606007, arXiv:0705.4527]. We introduce a SUSY formulation of the quantum Hall effect on supermanifolds. ...
  • Symmetries of Spin Calogero Models 
    Caudrelier, V.; Crampé, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We investigate the symmetry algebras of integrable spin Calogero systems constructed from Dunkl operators associated to finite Coxeter groups. Based on two explicit examples, we show that the common view of associating one ...
  • Symmetry Extensions and Their Physical Reasons in the Kinetic and Hydrodynamic Plasma Models 
    Taranov, V.B. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    Characteristic examples of continuous symmetries in hydrodynamic plasma theory (partial differential equations) and in kinetic Vlasov-Maxwell models (integro-differential equations) are considered. Possible symmetry ...
  • Symmetry Transformation in Extended Phase Space: the Harmonic Oscillator in the Husimi Representation 
    Bahrami, S.; Nasiri, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    In a previous work the concept of quantum potential is generalized into extended phase space (EPS) for a particle in linear and harmonic potentials. It was shown there that in contrast to the Schrödinger quantum mechanics ...
  • The Fundamental k-Form and Global Relations 
    Anthony C.L. Ashton (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    In [Proc. Roy. Soc. London Ser. A 453 (1997), no. 1962, 1411-1443] A.S. Fokas introduced a novel method for solving a large class of boundary value problems associated with evolution equations. This approach relies on the ...
