  • Strictly Positive Definite Kernels on a Product of Spheres II 
    Guella, J.C.; Menegatto, V.A.; Peron, A.P. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We present, among other things, a necessary and sufficient condition for the strict positive definiteness of an isotropic and positive definite kernel on the cartesian product of a circle and a higher dimensional sphere. ...
  • Symmetries of Lorentzian Three-Manifolds with Recurrent Curvature 
    Calvaruso, G.; Zaeim, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    Locally homogeneous Lorentzian three-manifolds with recurrect curvature are special examples of Walker manifolds, that is, they admit a parallel null vector field. We obtain a full classification of the symmetries of these ...
  • The Asymptotic Expansion of Kummer Functions for Large Values of the α-Parameter, and Remarks on a Paper by Olver 
    Volkmer, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    It is shown that a known asymptotic expansion of the Kummer function U(a,b,z) as a tends to infinity is valid for z on the full Riemann surface of the logarithm. A corresponding result is also proved in a more general ...
  • The Co-Points of Rays are Cut Points of Upper Level Sets for Busemann Functions 
    Sabau, S.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We show that the co-rays to a ray in a complete non-compact Finsler manifold contain geodesic segments to upper level sets of Busemann functions. Moreover, we characterise the co-point set to a ray as the cut locus of such ...
  • The Hojman Construction and Hamiltonization of Nonholonomic Systems 
    Bizyaev, I.A.; Borisov, A.V.; Mamaev, I.S. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In this paper, using the Hojman construction, we give examples of various Poisson brackets which differ from those which are usually analyzed in Hamiltonian mechanics. They possess a nonmaximal rank, and in the general ...
  • The Index of Dirac Operators on Incomplete Edge Spaces 
    Albin, P.; Gell-Redman, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We derive a formula for the index of a Dirac operator on a compact, even-dimensional incomplete edge space satisfying a ''geometric Witt condition''. We accomplish this by cutting off to a smooth manifold with boundary, ...
  • The Multi-Orientable Random Tensor Model, a Review 
    Tanasa, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    After its introduction (initially within a group field theory framework) in [Tanasa A., J. Phys. A: Math. Theor. 45 (2012), 165401, 19 pages, arXiv:1109.0694], the multi-orientable (MO) tensor model grew over the last years ...
  • The Quaternions and Bott Periodicity Are Quantum Hamiltonian Reductions 
    Johnson-Freyd, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We show that the Morita equivalences Cliff(4)≃H, Cliff(7)≃Cliff(−1), and Cliff(8)≃R arise from quantizing the Hamiltonian reductions R⁰|4//Spin(3), R⁰|⁷//G₂, and R⁰|⁸//Spin(7), respectively.
  • The Third, Fifth and Sixth Painlevé Equations on Weighted Projective Spaces 
    Chiba, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    The third, fifth and sixth Painlevé equations are studied by means of the weighted projective spaces CP³(p,q,r,s) with suitable weights (p,q,r,s) determined by the Newton polyhedrons of the equations. Singular normal forms ...
  • The Transition Probability of the q-TAZRP (q-Bosons) with Inhomogeneous Jump Rates 
    Wang, D.; Waugh, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In this paper we consider the q-deformed totally asymmetric zero range process (q-TAZRP), also known as the q-boson (stochastic) particle system, on the Z lattice, such that the jump rate of a particle depends on the site ...
  • Toda Equations and Piecewise Polynomiality for Mixed Double Hurwitz Numbers 
    Goulden, I.P.; Guay-Paquet, M.; Novak, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    This article introduces mixed double Hurwitz numbers, which interpolate combinatorially between the classical double Hurwitz numbers studied by Okounkov and the monotone double Hurwitz numbers introduced recently by Goulden, ...
  • Uniform Asymptotic Expansion for the Incomplete Beta Function 
    Nemes, G.; Olde Daalhuis, A.B. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In [Temme N.M., Special functions. An introduction to the classical functions of mathematical physics, A Wiley-Interscience Publication, John Wiley & Sons, Inc., New York, 1996, Section 11.3.3.1] a uniform asymptotic ...
  • Universal Lie Formulas for Higher Antibrackets 
    Manetti, M.; Ricciardi, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We prove that the hierarchy of higher antibrackets (aka higher Koszul brackets, aka Koszul braces) of a linear operator Δ on a commutative superalgebra can be defined by some universal formulas involving iterated ...
  • Un-Reduction of Systems of Second-Order Ordinary Differential Equations 
    García-Toraño Andrés, E.; Mestdag, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In this paper we consider an alternative approach to ''un-reduction''. This is the process where one associates to a Lagrangian system on a manifold a dynamical system on a principal bundle over that manifold, in such a ...
  • Variational Sequences, Representation Sequences and Applications in Physics 
    Palese, M.; Rossi, O.; Winterroth, E.; Musilová, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    This paper is a review containing new original results on the finite order variational sequence and its different representations with emphasis on applications in the theory of variational symmetries and conservation laws ...
  • Variational Tricomplex, Global Symmetries and Conservation Laws of Gauge Systems 
    Sharapov, A.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    Using the concept of variational tricomplex endowed with a presymplectic structure, we formulate the general notion of symmetry. We show that each generalized symmetry of a gauge system gives rise to a sequence of conservation ...
  • 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 ...
  • Zeros of Quasi-Orthogonal Jacobi Polynomials 
    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, ...
