  • Galois Groups of Difference Equations of Order Two on Elliptic Curves 
    Dreyfus, T.; Roques, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    This paper is concerned with difference equations on elliptic curves. We establish some general properties of the difference Galois groups of equations of order two, and give applications to the calculation of some difference ...
  • Gauge Theories on Deformed Spaces 
    Blaschke, D.N.; Kronberger, E.; René I.P. Sedmik; Wohlgenannt, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, ...
  • Gauge Theory on Twisted κ-Minkowski: Old Problems and Possible Solutions 
    Dimitrijević, M.; Jonke, L.; Pachoł, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    We review the application of twist deformation formalism and the construction of noncommutative gauge theory on κ-Minkowski space-time. We compare two different types of twists: the Abelian and the Jordanian one. In each ...
  • General Boundary Formulation for n-Dimensional Classical Abelian Theory with Corners 
    Díaz-Marín, H.G. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We propose a general reduction procedure for classical field theories provided with abelian gauge symmetries in a Lagrangian setting. These ideas come from an axiomatic presentation of the general boundary formulation (GBF) ...
  • Generalised Chern-Simons Theory and G₂-Instantons over Associative Fibrations 
    Henrique N. Sá Earp (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    Adjusting conventional Chern-Simons theory to G₂-manifolds, one describes G₂-instantons on bundles over a certain class of 7-dimensional flat tori which fiber non-trivially over T⁴, by a pullback argument. Moreover, if ...
  • Generalized Bessel function of Type D 
    Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We write down the generalized Bessel function associated with the root system of type D by means of multivariate hypergeometric series. Our hint comes from the particular case of the Brownian motion in the Weyl chamber of type D.
  • Generalized Clifford Algebras as Algebras in Suitable Symmetric Linear Gr-Categories 
    Cheng, T.; Huang, H.-L.; Yang, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    By viewing Clifford algebras as algebras in some suitable symmetric Gr-categories, Albuquerque and Majid were able to give a new derivation of some well known results about Clifford algebras and to generalize them. Along ...
  • Generalized Coefficients for Hopf Cyclic Cohomology 
    Hassanzadeh, M.; Kucerovsky, D.; Rangipour, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    A category of coefficients for Hopf cyclic cohomology is defined. It is shown that this category has two proper subcategories of which the smallest one is the known category of stable anti Yetter-Drinfeld modules. The ...
  • Generalized Convolution Roots of Positive Definite Kernels on Complex Spheres 
    Barbosa, V.S.; Menegatto, V.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    Convolution is an important tool in the construction of positive definite kernels on a manifold. This contribution provides conditions on an L²-positive definite and zonal kernel on the unit sphere of Cq in order that the ...
  • Generalized Deformed Commutation Relations with Nonzero Minimal Uncertainties in Position and/or Momentum and Applications to Quantum Mechanics 
    Quesne, C.; Tkachuk, V.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Two generalizations of Kempf's quadratic canonical commutation relation in one dimension are considered. The first one is the most general quadratic commutation relation. The corresponding nonzero minimal uncertainties in ...
  • Generalized Ellipsoidal and Sphero-Conal Harmonics 
    Volkmer, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    Classical ellipsoidal and sphero-conal harmonics are polynomial solutions of the Laplace equation that can be expressed in terms of Lamé polynomials. Generalized ellipsoidal and sphero-conal harmonics are polynomial solutions ...
  • Generalized Fuzzy Torus and its Modular Properties 
    Schreivogl, P.; Steinacker, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We consider a generalization of the basic fuzzy torus to a fuzzy torus with non-trivial modular parameter, based on a finite matrix algebra. We discuss the modular properties of this fuzzy torus, and compute the matrix ...
  • Generalized Hasimoto Transform of One-Dimensional Dispersive Flows into Compact Riemann Surfaces 
    Onodera, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We study the structure of differential equations of one-dimensional dispersive flows into compact Riemann surfaces. These equations geometrically generalize two-sphere valued systems modeling the motion of vortex filament. ...
  • Generalized Heisenberg Algebras, SUSYQM and Degeneracies: Infinite Well and Morse Potential 
    Hussin, V.; Marquette, I. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We consider classical and quantum one and two-dimensional systems with ladder operators that satisfy generalized Heisenberg algebras. In the classical case, this construction is related to the existence of closed trajectories. ...
  • Generalized Nonanalytic Expansions, PT-Symmetry and Large-Order Formulas for Odd Anharmonic Oscillators 
    Jentschura, U.D.; Surzhykov, A.; Zinn-Justin, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    The concept of a generalized nonanalytic expansion which involves nonanalytic combinations of exponentials, logarithms and powers of a coupling is introduced and its use illustrated in various areas of physics. Dispersion ...
  • Generalized Potts-Models and their Relevance for Gauge Theories 
    Wipf, A.; Heinzl, T.; Kaestner, T.; Wozar, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We study the Polyakov loop dynamics originating from finite-temperature Yang-Mills theory. The effective actions contain center-symmetric terms involving powers of the Polyakov loop, each with its own coupling. For a ...
  • Generalized Stieltjes Transforms of Compactly-Supported Probability Distributions: Further Examples 
    Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    For two families of beta distributions, we show that the generalized Stieltjes transforms of their elements may be written as elementary functions (powers and fractions) of the Stieltjes transform of the Wigner distribution. ...
  • Generalized Symmetries of Massless Free Fields on Minkowski Space 
    Pohjanpelto, J.; Anco, S.C. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    A complete and explicit classification of generalized, or local, symmetries of massless free fields of spin s ≥ 1/2 is carried out. Up to equivalence, these are found to consists of the conformal symmetries and their duals, ...
  • Generating Operator of XXX or Gaudin Transfer Matrices Has Quasi-Exponential Kernel 
    Mukhin, E.; Tarasov, V.; Varchenko, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We show that the difference equation Df = 0 for an M-valued function f has a basis of solutions consisting of quasi-exponentials.
  • Generating Series for Nested Bethe Vectors 
    Khoroshkin, S.; Pakuliak, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We reformulate nested relations between off-shell Uq(^glN) Bethe vectors as a certain equation on generating series of strings of the composed Uq(^glN) currents. Using inversion of the generating series we find a new type ...
