  • Entire bivariate functions of unbounded index in each direction 
    Bandura, A.I.; Skaskiv, O.B. (Нелінійні коливання, 2018)
    We investigate a class of entire functions f(z₁, z₂) with property ∀b= (b₁, b₂) ∈ C² \ {0} ∀ z⁰₁, z⁰₂ ∈ C, the function f(z⁰₁ + tb₁, z⁰₂ + tb₂), as a function of one variable t ∈ C, has a bounded index but the function ...
  • Entire solutions of the Euler—Poisson equations 
    Belyaev, A.V. (Український математичний журнал, 2004)
    All entire solutions of Euler—Poisson equations are presented.
  • Entropy of Quantum Black Holes 
    Kaul, R.K. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    In the Loop Quantum Gravity, black holes (or even more general Isolated Horizons) are described by a SU(2) Chern-Simons theory. There is an equivalent formulation of the horizon degrees of freedom in terms of a U(1) gauge ...
  • Entropy of the Shift on II₁-representations of the Group S(∞) 
    Boyko, M.S.; Nessonov, N.I. (Український математичний вісник, 2005)
    We have obtained the explicit formulae for the CNT-entropy of the shift on II₁-representations of the infinite symmetric group S(∞) in terms of Thoma-parameters.
  • Entropy solutions of Dirichlet problem for a class of nonlinear elliptic fourth order equations with L¹-data 
    Kovalevsky, A.A. (Нелинейные граничные задачи, 1999)
    We consider the question on solvability and uniqueness of entropy solutions of Dirichlet problem for a class of nonlinear elliptic fourth order equations with L¹-right-hand sides. We restrict ourselves with equations of ...
  • Entropy solutions of Dirichlet problem for a class of nonlinear elliptic high-order equations with L¹-data 
    Kovalevsky, A.A. (Нелинейные граничные задачи, 2002)
    In this paper we study Dirichlet problem for nonlinear elliptic high-order equations with coefficients satisfying a strengthened ellipticity condition. A class of nonlinear high-order equations with such a condition on ...
  • Enumeration of strong dichotomy patterns 
    Agustín-Aquino, O.A. (Algebra and Discrete Mathematics, 2018)
    We apply the version of Pólya-Redfield theory obtained by White to count patterns with a given automorphism group to the enumeration of strong dichotomy patterns, that is, we count bicolor patterns of Z2k with respect to ...
  • Envelope modulational instability in the nonlinear dissipative transmission line 
    Kengne, E. (Нелінійні коливання, 2002)
    Biinductance LC circuit is considered and envelope modulation is reduced to the complex nonlinear Schrodinger (CNLS) equation. The Benjamin ¨ – Feir (or modulational, as it is sometimes called) instability for the CNLS ...
  • E-Orbit Functions 
    Klimyk, A.U.; Patera, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We review and further develop the theory of E-orbit functions. They are functions on the Euclidean space En obtained from the multivariate exponential function by symmetrization by means of an even part We of a Weyl group ...
  • Epsilon Systems on Geometric Crystals of Type An 
    Nakashima, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We introduce an epsilon system on a geometric crystal of type An, which is a certain set of rational functions with some nice properties. We shall show that it is equipped with a product structure and that it is invariant ...
  • Equilibrium and Nonequilibrium States of the Model Fröhlich–Peierls Hamiltonian 
    Petrina, D.Ya. (Український математичний журнал, 2003)
    The model Fröhlich–Peierls Hamiltonian for electrons interacting with phonons only in some infinite discrete modes is considered. It is shown that, in the equilibrium case, this model is thermodynamically equivalent to the ...
  • Equilibrium in quantum systems of particles with magnetic interaction. Fermi and bose statistics 
    Skrypnik, W.I. (Український математичний журнал, 1997)
    Quantum systems of particles interacting via an effective electromagnetic potential with zero electrostatic component are considered (magnetic interaction). It is assumed that the j th component of the effective potential ...
  • Equivalence of Carter diagrams 
    Stekolshchik, R. (Algebra and Discrete Mathematics, 2017)
    We introduce the equivalence relation ρ on the set of Carter diagrams and construct an explicit transformation of any Carter diagram containing l-cycles with l>4 to an equivalent Carter diagram containing only 4-cycles. ...
  • Equivalent and Alternative Forms for BF Gravity with Immirzi Parameter 
    Montesinos, M.; Velázquez, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    A detailed analysis of the BF formulation for general relativity given by Capovilla, Montesinos, Prieto, and Rojas is performed. The action principle of this formulation is written in an equivalent form by doing a ...
  • Equivariance, Variational Principles, and the Feynman Integral 
    Svetlichny, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We argue that the variational calculus leading to Euler's equations and Noether's theorem can be replaced by equivariance and invariance conditions avoiding the action integral. We also speculate about the origin of ...
  • Equivariant Gromov-Witten Invariants of Algebraic GKM Manifolds 
    Liu, Chiu-Chu Melissa; Sheshmani, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    An algebraic GKM manifold is a non-singular algebraic variety equipped with an algebraic action of an algebraic torus, with only finitely many torus fixed points and finitely many 1-dimensional orbits. In this expository ...
  • Equivariant Join and Fusion of Noncommutative Algebras 
    Dąbrowski, L.; Hadfield, T.; Hajac, P.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We translate the concept of the join of topological spaces to the language of C∗-algebras, replace the C∗-algebra of functions on the interval [0,1] with evaluation maps at 0 and 1 by a unital C∗-algebra C with appropriate ...
  • Erlangen Program at Large-1: Geometry of Invariants 
    Kisil, V.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    This paper presents geometrical foundation for a systematic treatment of three main (elliptic, parabolic and hyperbolic) types of analytic function theories based on the representation theory of SL₂(R) group. We describe ...

    Rogers, C.; Clarkson, P.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    A class of nonlinear Schrödinger equations involving a triad of power law terms together with a de Broglie-Bohm potential is shown to admit symmetry reduction to a hybrid Ermakov-Painlevé II equation which is linked, in ...
  • Essential Parabolic Structures and Their Infinitesimal Automorphisms 
    Alt, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    Using the theory of Weyl structures, we give a natural generalization of the notion of essential conformal structures and conformal Killing fields to arbitrary parabolic geometries. We show that a parabolic structure is ...
