  • 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 ...
  • Pseudo-Bosons from Landau Levels 
    Bagarello, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We construct examples of pseudo-bosons in two dimensions arising from the Hamiltonian for the Landau levels. We also prove a no-go result showing that non-linear combinations of bosonic creation and annihilation operators ...
  • PT Symmetric Schrödinger Operators: Reality of the Perturbed Eigenvalues 
    Caliceti, E.; Cannata, F.; Graffi, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We prove the reality of the perturbed eigenvalues of some PT symmetric Hamiltonians of physical interest by means of stability methods. In particular we study 2-dimensional generalized harmonic oscillators with polynomial ...

    Asherova, R.M.; Burdík, Č.; Havlíček, M.; Smirnov, Y.F.; Tolstoy, V.N. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    For the quantum algebra Uq(gl(n+1)) in its reduction on the subalgebra Uq(gl(n)) an explicit description of a Mickelsson-Zhelobenko reduction Z-algebra Zq(gl(n+1),gl(n)) is given in terms of the generators and their defining ...
  • Q-system Cluster Algebras, Paths and Total Positivity 
    di Francesko, P.; Kedem, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    In the first part of this paper, we provide a concise review of our method of solution of the Ar Q-systems in terms of the partition function of paths on a weighted graph. In the second part, we show that it is possible ...
  • Quantum Fields on Noncommutative Spacetimes: Theory and Phenomenology 
    Balachandran, A.P.; Ibort, A.; Marmo, G.; Martone, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance. We present the latest development in the field, in particular the ...
  • Quantum Integrable 1D anyonic Models: Construction through Braided Yang-Baxter Equation 
    Kundu, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Applying braided Yang-Baxter equation quantum integrable and Bethe ansatz solvable 1D anyonic lattice and field models are constructed. Along with known models we discover novel lattice anyonic and q-anyonic models as well ...
  • Quantum Isometry Group for Spectral Triples with Real Structure 
    Goswami, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Given a spectral triple of compact type with a real structure in the sense of [Dabrowski L., J. Geom. Phys. 56 (2006), 86-107] (which is a modification of Connes' original definition to accommodate examples coming from ...
  • Quantum Spacetime: a Disambiguation 
    Piacitelli, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We review an approach to non-commutative geometry, where models are constructed by quantisation of the coordinates. In particular we focus on the full DFR model and its irreducible components; the (arbitrary) restriction ...
  • Quiver Varieties with Multiplicities, Weyl Groups of Non-Symmetric Kac-Moody Algebras, and Painlevé Equations 
    Yamakawa, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    To a finite quiver equipped with a positive integer on each of its vertices, we associate a holomorphic symplectic manifold having some parameters. This coincides with Nakajima's quiver variety with no stability parameter/framing ...
  • Singular Reduction of Generalized Complex Manifolds 
    Goldberg, T.E. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    In this paper, we develop results in the direction of an analogue of Sjamaar and Lerman's singular reduction of Hamiltonian symplectic manifolds in the context of reduction of Hamiltonian generalized complex manifolds (in ...
  • Sklyanin Determinant for Reflection Algebra 
    Rozhkovskaya, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Reflection algebras is a class of algebras associated with integrable models with boundaries. The coefficients of Sklyanin determinant generate the center of the reflection algebra. We give a combinatorial description of ...
  • Snyder Space-Time: K-Loop and Lie Triple System 
    Girelli, F. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Different deformations of the Poincaré symmetries have been identified for various non-commutative spaces (e.g. κ-Minkowski, sl(2,R), Moyal). We present here the deformation of the Poincaré symmetries related to Snyder ...
  • Solitary Waves in Massive Nonlinear SN-Sigma Models 
    Izquierdo, A.A.; González León, M.A.; de la Torre Mayado, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The solitary waves of massive (1+1)-dimensional nonlinear SN-sigma models are unveiled. It is shown that the solitary waves in these systems are in one-to-one correspondence with the separatrix trajectories in the repulsive ...

    Cagnache, E.; Wallet, J.C. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The spectral distance for noncommutative Moyal planes is considered in the framework of a non compact spectral triple recently proposed as a possible noncommutative analog of non compact Riemannian spin manifold. An explicit ...
  • Strong Field, Noncommutative QED 
    Ilderton, A.; Lundin, J.; Marklund, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We review the effects of strong background fields in noncommutative QED. Beginning with the noncommutative Maxwell and Dirac equations, we describe how combined noncommutative and strong field effects modify the propagation ...
  • Supersymmetrical Separation of Variables in Two-Dimensional Quantum Mechanics 
    Ioffe, M.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Two different approaches are formulated to analyze two-dimensional quantum models which are not amenable to standard separation of variables. Both methods are essentially based on supersymmetrical second order intertwining ...

    Schmidtt, D.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We couple two copies of the supersymmetric mKdV hierarchy by means of the algebraic dressing technique. This allows to deduce the whole set of (N,N) supersymmetry transformations of the relativistic sector of the extended ...
