  • Painlevé Analysis and Similarity Reductions for the Magma Equation 
    Harris, S.E.; Clarkson, P.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    In this paper, we examine a generalized magma equation for rational values of two parameters, m and n. Firstly, the similarity reductions are found using the Lie group method of infinitesimal transformations. The Painlevé ...
  • Para-Grassmannian Coherent and Squeezed States for Pseudo-Hermitian q-Oscillator and their Entanglement 
    Maleki, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In this paper, q-deformed oscillator for pseudo-Hermitian systems is investigated and pseudo-Hermitian appropriate coherent and squeezed states are studied. Also, some basic properties of these states is surveyed. The ...
  • Para-Grassmann variables and coherent states 
    Cabra, D.C.; Moreno, E.F.; Tanasă, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    The definitions of para-Grassmann variables and q-oscillator algebras are recalled. Some new properties are given. We then introduce appropriate coherent states as well as their dual states. This allows us to obtain a ...
  • Parallelisms & Lie Connections 
    Blázquez-Sanz, D.; Casale, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The aim of this article is to study rational parallelisms of algebraic varieties by means of the transcendence of their symmetries. The nature of this transcendence is measured by a Galois group built from the Picard-Vessiot ...
  • Parameterizing the Simplest Grassmann-Gaussian Relations for Pachner Move 3-3 
    Korepanov, I.G.; Sadykov, N.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We consider relations in Grassmann algebra corresponding to the four-dimensional Pachner move 3-3, assuming that there is just one Grassmann variable on each 3-face, and a 4-simplex weight is a Grassmann-Gaussian exponent ...
  • Partial Sums of Two Quartic q-Series 
    Chu, W.; Wang, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    The partial sums of two quartic basic hypergeometric series are investigated by means of the modified Abel lemma on summation by parts. Several summation and transformation formulae are consequently established.
  • Particle Motion in Monopoles and Geodesics on Cones 
    Mayrand, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The equations of motion of a charged particle in the field of Yang's SU(2) monopole in 5-dimensional Euclidean space are derived by applying the Kaluza-Klein formalism to the principal bundle R⁸∖{0}→R⁵∖{0} obtained by ...
  • Part III, Free Actions of Compact Quantum Groups on C*-Algebras 
    Schwieger, K.; Wagner, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We study and classify free actions of compact quantum groups on unital C∗-algebras in terms of generalized factor systems. Moreover, we use these factor systems to show that all finite coverings of irrational rotation ...
  • Partner Symmetries, Group Foliation and ASD Ricci-Flat Metrics without Killing Vectors 
    Sheftel, M.B.; Malykh, A.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We demonstrate how a combination of our recently developed methods of partner symmetries, symmetry reduction in group parameters and a new version of the group foliation method can produce noninvariant solutions of complex ...
  • Path Integrals on Euclidean Space Forms 
    Capobianco, G.; Reartes, W. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    In this paper we develop a quantization method for flat compact manifolds based on path integrals. In this method the Hilbert space of holomorphic functions in the complexification of the manifold is used. This space is a ...
  • Paths and Tableaux Descriptions of Jacobi-Trudi Determinant Associated with Quantum Affine Algebra of Type Cn 
    Nakai, W.; Nakanishi, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We study the Jacobi-Trudi-type determinant which is conjectured to be the q-character of a certain, in many cases irreducible, finite-dimensional representation of the quantum affine algebra of type Cn. Like the Dn case ...
  • Pentagon Relations in Direct Sums and Grassmann Algebras 
    Korepanov, I.G.; Sadykov, N.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We construct vast families of orthogonal operators obeying pentagon relation in a direct sum of three n-dimensional vector spaces. As a consequence, we obtain pentagon relations in Grassmann algebras, making a far reaching ...
  • Periodic and Solitary Travelling-Wave Solutions of an Extended Reduced Ostrovsky Equation 
    Parkes, E.J. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    Periodic and solitary travelling-wave solutions of an extended reduced Ostrovsky equation are investigated. Attention is restricted to solutions that, for the appropriate choice of certain constant parameters, reduce to ...
  • Periodic and Solitary Wave Solutions of Two Component Zakharov-Yajima-Oikawa System, Using Madelung's Approach 
    Visinescu, A.; Grecu, D.; Fedele, R.; De Nicola, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    Using the multiple scales method, the interaction between two bright and one dark solitons is studied. Provided that a long wave-short wave resonance condition is satisfied, the two-component Zakharov-Yajima-Oikawa (ZYO) ...
  • Periodic GMP Matrices 
    Eichinger, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We recall criteria on the spectrum of Jacobi matrices such that the corresponding isospectral torus consists of periodic operators. Motivated by those known results for Jacobi matrices, we define a new class of operators ...
  • Periodic Vortex Streets and Complex Monodromy 
    Hemery, A.D.; Veselov, P.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The explicit constructions of periodic and doubly periodic vortex relative equilibria using the theory of monodromy-free Schrödinger operators are described. Several concrete examples with the qualitative analysis of the ...
  • Period Matrices of Real Riemann Surfaces and Fundamental Domains 
    Giavedoni, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    For some positive integers g and n we consider a subgroup Gg,n of the 2g-dimensional modular group keeping invariant a certain locus Wg,n in the Siegel upper half plane of degree g. We address the problem of describing a ...

    Militello, B.; Aniello, P.; Messina, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    A novel perturbative treatment of the time evolution operator of a quantum system is applied to the model describing a Raman-driven trapped ion in order to obtain a suitable 'effective model'. It is shown that the associated ...
  • Peterson's Deformations of higher dimensional quadrics 
    Dincă, I.I. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We provide the first explicit examples of deformations of higher dimensional quadrics: a straightforward generalization of Peterson's explicit 1-dimensional family of deformations in C³ of 2-dimensional general quadrics ...
  • Phase Space of Rolling Solutions of the Tippe Top 
    Glad, S.T.; Petersson, D.; Rauch-Wojciechowski, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Equations of motion of an axially symmetric sphere rolling and sliding on a plane are usually taken as model of the tippe top. We study these equations in the nonsliding regime both in the vector notation and in the Euler ...
