  • Effects of a Maximal Energy Scale in Thermodynamics for Photon Gas and Construction of Path Integral 
    Das, S.; Pramanik, S.; Ghosh, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    In this article, we discuss some well-known theoretical models where an observer-independent energy scale or a length scale is present. The presence of this invariant scale necessarily deforms the Lorentz symmetry. We study ...
  • Effects of Quark Interactions on Dynamical Chiral Symmetry Breaking by a Magnetic Field 
    Hiller, B.; Osipov, A.A.; Blin, A.H.; Providência, João da (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    It is shown how the strong interaction dynamics of a multi-quark Lagrangian affects the catalysis of dynamical symmetry breaking by a constant magnetic field in (3+1) dimensions. Attention is drawn to the local minima ...
  • Eigenfunction Expansions of Functions Describing Systems with Symmetries 
    Kachuryk, I.; Klimyk, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Physical systems with symmetries are described by functions containing kinematical and dynamical parts. We consider the case when kinematical symmetries are described by a noncompact semisimple real Lie group G. Then ...
  • Eigenvalue Estimates of the spinc Dirac Operator and Harmonic Forms on Kähler-Einstein Manifolds 
    Nakad, R.; Pilca, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We establish a lower bound for the eigenvalues of the Dirac operator defined on a compact Kähler-Einstein manifold of positive scalar curvature and endowed with particular spinc structures. The limiting case is characterized ...
  • Eigenvalues of Killing Tensors and Separable Webs on Riemannian and Pseudo-Riemannian Manifolds 
    Chanu, C.; Rastelli, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Given a n-dimensional Riemannian manifold of arbitrary signature, we illustrate an algebraic method for constructing the coordinate webs separating the geodesic Hamilton-Jacobi equation by means of the eigenvalues of m ≤ ...
  • Eigenvectors of Open Bazhanov-Stroganov Quantum Chain 
    Iorgov, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    In this contribution we give an explicit formula for the eigenvectors of Hamiltonians of open Bazhanov-Stroganov quantum chain. The Hamiltonians of this quantum chain is defined by the generation polynomial An(λ) which is ...
  • Einstein Gravity, Lagrange-Finsler Geometry, and Nonsymmetric Metrics 
    Vacaru, S.I. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We formulate an approach to the geometry of Riemann-Cartan spaces provided with nonholonomic distributions defined by generic off-diagonal and nonsymmetric metrics inducing effective nonlinear and affine connections. Such ...
  • Einstein-Riemann gravity on deformed spaces 
    Wess, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    A differential calculus, differential geometry and the E-R Gravity theory are studied on noncommutative spaces. Noncommutativity is formulated in the star product formalism. The basis for the gravity theory is the infinitesimal ...
  • Electroweak Interaction Model with an Undegenerate Double Symmetry 
    Slad, L.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    The initial P-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry. Among the transformation parameters of this ...
  • Elliptic Biorthogonal Polynomials Connected with Hermite's Continued Fraction 
    Vinet, L.; Zhedanov, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We study a family of the Laurent biorthogonal polynomials arising from the Hermite continued fraction for a ratio of two complete elliptic integrals. Recurrence coefficients, explicit expression and the weight function for ...
  • Elliptic Determinantal Processes and Elliptic Dyson Models 
    Katori, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We introduce seven families of stochastic systems of interacting particles in one-dimension corresponding to the seven families of irreducible reduced affine root systems. We prove that they are determinantal in the sense ...
  • Elliptic Hypergeometric Laurent Biorthogonal Polynomials with a Dense Point Spectrum on the Unit Circle 
    Tsujimoto, S.; Zhedanov, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    Using the technique of the elliptic Frobenius determinant, we construct new elliptic solutions of the QD-algorithm. These solutions can be interpreted as elliptic solutions of the discrete-time Toda chain as well. As a ...
  • Elliptic Hypergeometric Solutions to Elliptic Difference Equations 
    Magnus, A.P. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    It is shown how to define difference equations on particular lattices {xn}, n ∊ Z, made of values of an elliptic function at a sequence of arguments in arithmetic progression (elliptic lattice). Solutions to special ...
  • Elliptic Hypergeometric Summations by Taylor Series Expansion and Interpolation 
    Schlosser, M.J.; Yoo, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We use elliptic Taylor series expansions and interpolation to deduce a number of summations for elliptic hypergeometric series. We extend to the well-poised elliptic case results that in the q-case have previously been ...
  • Embeddings of the Racah Algebra into the Bannai-Ito Algebra 
    Genest, V.X.; Vinet, L.; Zhedanov, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    Embeddings of the Racah algebra into the Bannai-Ito algebra are proposed in two realizations. First, quadratic combinations of the Bannai-Ito algebra generators in their standard realization on the space of polynomials are ...

    Stern, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We construct exact solutions to noncommutative gravity following the formulation of Chamseddine and show that they are in general accompanied by Abelian gauge fields which are first order in the noncommutative scale. This ...

    Bilson-Thompson, S.; Hackett, J.; Kauffman, L.; Wan, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    We review and present a few new results of the program of emergent matter as braid excitations of quantum geometry that is represented by braided ribbon networks. These networks are a generalisation of the spin networks ...
  • Emergent Models for Gravity: an Overview of Microscopic Models 
    Sindoni, L. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    We give a critical overview of various attempts to describe gravity as an emergent phenomenon, starting from examples of condensed matter physics, to arrive to more sophisticated pregeometric models. The common line of ...

    Nagasawa, T.; Ohya, S.; Sakamoto, K.; Sakamoto, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We show that quantum mechanical supersymmetries are emerged in Kaluza-Klein spectrum of linearized gravity in several warped backgrounds as a consequence of higher-dimensional general coordinate invariance. These emergent ...
