  • Wall Crossing, Discrete Attractor Flow and Borcherds Algebra 
    Cheng, Miranda C.N.; Verlinde, E.P. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The appearance of a generalized (or Borcherds-) Kac-Moody algebra in the spectrum of BPS dyons in N=4, d=4 string theory is elucidated. From the low-energy supergravity analysis, we identify its root lattice as the lattice ...
  • Wavelet-Based Quantum Field Theory 
    Altaisky, M.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    The Euclidean quantum field theory for the fields φΔx(x), which depend on both the position x and the resolution Δx, constructed in SIGMA 2 (2006), 046, on the base of the continuous wavelet transform, is considered. The ...
  • Weakly Nonlocal Hamiltonian Structures: Lie Derivative and Compatibility 
    Sergyeyev, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We show that under certain technical assumptions any weakly nonlocal Hamiltonian structure compatible with a given nondegenerate weakly nonlocal symplectic structure J can be written as the Lie derivative of J −1 along a ...
  • Weighted Tensor Products of Joyal Species, Graphs, and Charades 
    Street, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    Motivated by the weighted Hurwitz product on sequences in an algebra, we produce a family of monoidal structures on the category of Joyal species. We suggest a family of tensor products for charades. We begin by seeing ...
  • Weil Representation of a Generalized Linear Group over a Ring of Truncated Polynomials over a Finite Field Endowed with a Second Class Involution 
    Gutiérrez Frez, L.; Pantoja, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We construct a complex linear Weil representation ρ of the generalized special linear group G=SL¹∗(2,An) (An=K[x]/⟨xⁿ⟩, K the quadratic extension of the finite field k of q elements, q odd), where An is endowed with a ...
  • Werner's Measure on Self-Avoiding Loops and Welding 
    Chavez, A.; Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    Werner's conformally invariant family of measures on self-avoiding loops on Riemann surfaces is determined by a single measure μ0 on self-avoiding loops in C∖{0} which surround 0. Our first major objective is to show that ...
  • Whitham's Method and Dubrovin-Novikov Bracket in Single-Phase and Multiphase Cases 
    Maltsev, A.Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    In this paper we examine in detail the procedure of averaging of the local field-theoretic Poisson brackets proposed by B.A. Dubrovin and S.P. Novikov for the method of Whitham. The main attention is paid to the questions ...
  • Who's Afraid of the Hill Boundary? 
    Montgomery, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The Jacobi-Maupertuis metric allows one to reformulate Newton's equations as geodesic equations for a Riemannian metric which degenerates at the Hill boundary. We prove that a JM geodesic which comes sufficiently close to ...
  • Why Do the Relativistic Masses and Momenta of Faster-than-Light Particles Decrease as their Speeds Increase? 
    Madarász, J.X.; Stannett, M.; Székely, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    It has recently been shown within a formal axiomatic framework using a definition of four-momentum based on the Stückelberg-Feynman-Sudarshan-Recami ''switching principle'' that Einstein's relativistic dynamics is logically ...
  • Wigner Distribution Functions and the Representation of Canonical Transformations in Time-Dependent Quantum Mechanics 
    Schuch, D.; Moshinsky, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    For classical canonical transformations, one can, using the Wigner transformation, pass from their representation in Hilbert space to a kernel in phase space. In this paper it will be discussed how the time-dependence of ...
  • Wigner Quantization of Hamiltonians Describing Harmonic Oscillators Coupled by a General Interaction Matri 
    Regniers, G.; Van der Jeugt, Joris (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    In a system of coupled harmonic oscillators, the interaction can be represented by a real, symmetric and positive definite interaction matrix. The quantization of a Hamiltonian describing such a system has been done in the ...
  • WKB Approximation in Noncommutative Gravity 
    Buric, M.; Madore, J.; Zoupanos, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the ...
  • Wong's Equations and Charged Relativistic Particles in Non-Commutative Space 
    Balasin, H.; Blaschke, D.N.; Gieres, F.; Schweda, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    In analogy to Wong's equations describing the motion of a charged relativistic point particle in the presence of an external Yang-Mills field, we discuss the motion of such a particle in non-commutative space subject to ...
  • Yang-Baxter Maps from the Discrete BKP Equation 
    Kakei, S.; Nimmo, J; Willox, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We construct rational and piecewise-linear Yang–Baxter maps for a general N-reduction of the discrete BKP equation.
  • Yangian of the Strange Lie Superalgebra of Qn₋₁ Type, Drinfel'd Approach 
    Stukopin, V. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    The Yangian of the strange Lie superalgebras in Drinfel'd realization is defined. The current system generators and defining relations are described.
  • Zamolodchikov Tetrahedral Equation and Higher Hamiltonians of 2d Quantum Integrable Systems 
    Talalaev, D.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The main aim of this work is to develop a method of constructing higher Hamiltonians of quantum integrable systems associated with the solution of the Zamolodchikov tetrahedral equation. As opposed to the result of V.V. ...
  • Zero Action on Perfect Crystals for Uq(G₂⁽¹⁾) 
    Misra, K.C.; Mohamad, M.; Okado, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The actions of 0-Kashiwara operators on the Uq'(GG₂⁽¹⁾)-crystal Bl in [Yamane S., J. Algebra 210 (1998), 440-486] are made explicit by using a similarity technique from that of a Uq'(D₄⁽³⁾)-crystal. It is shown that {Bl}l ...

    Bogoliubov, N.M.; Malyshev, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The special limit of the totally asymmetric zero range process of the low-dimensional non-equilibrium statistical mechanics described by the non-Hermitian Hamiltonian is considered. The calculation of the conditional ...

    Driver, K.; Jordaan, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We consider interlacing properties satisfied by the zeros of Jacobi polynomials in quasi-orthogonal sequences characterised by α>−1, −2<β<−1. We give necessary and sufficient conditions under which a conjecture by Askey, ...
  • Zeta Functions of Monomial Deformations of Delsarte Hypersurfaces 
    Kloosterman, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    Let Xλ and X′λ be monomial deformations of two Delsarte hypersurfaces in weighted projective spaces. In this paper we give a sufficient condition so that their zeta functions have a common factor. This generalises results ...
