  • Jacobi Matrix Pair and Dual Alternative q-Charlier Polynomials 
    Atakishiyev, N.M.; Klimyk, A.U. (Український математичний журнал, 2005)
    By using two operators representable by Jacobi matrices, we introduce a family of q-orthogonal polynomials, which turn out to be dual with respect to alternative q-Charlier polynomials. A discrete orthogonality relation ...
  • Jacobsthal-Lucas series and their applications 
    Pratsiovytyi, M.; Karvatsky, D. (Algebra and Discrete Mathematics, 2017)
    In this paper we study the properties of positive series such that its terms are reciprocals of the elements of Jacobsthal-Lucas sequence. In particular, we consider the properties of the set of incomplete sums as well as ...
  • James' Submodule Theorem and the Steinberg Module 
    Geck, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    James' submodule theorem is a fundamental result in the representation theory of the symmetric groups and the finite general linear groups. In this note we consider a version of that theorem for a general finite group with ...
  • Jordan-Schwinger Representations and Factorised Yang-Baxter Operators 
    Karakhanyan, D.; Kirschner, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The construction elements of the factorised form of the Yang-Baxter R operator acting on generic representations of q-deformed sl(n+1) are studied. We rely on the iterative construction of such representations by the ...

  • Junction Type Representations of the Temperley-Lieb Algebra and Associated Symmetries 
    Doikou, A.; Karaiskos, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Inspired by earlier works on representations of the Temperley-Lieb algebra we introduce a novel family of representations of the algebra. This may be seen as a generalization of the so called asymmetric twin representation. ...
  • J-дробова регуляризація лінійних некоректних рівнянь 
    Сявавко, М.С. (Український математичний журнал, 1996)
    На основі апарату неперервних J-дробів викладено метод розв'язання лінійних некоректних рівнянь у функціональних просторах. Знайдено мероморфний розв'язок регуляризованих рівнянь. Відмічено випадки зображення розв'язку ...
  • Kahler Geometry and Burgers' Vortices 
    Roulstone, I.; Banos, B.; Gibbon, J.D.; Roubtsov, V.N. (2009)
    We study the Navier-Stokes and Euler equations of incompressible hydrodynamics. Taking the divergence of the momentum equation leads, as usual, to a Poisson equation for the pressure: in this paper we study this equation ...
  • Kaleidoscopical configurations 
    Protasov, І.; Protasova, K. (Український математичний вісник, 2014)
    Let G be a group and X be a G-space with the action G × X → X, (g, x) → gx. A subset A of X is called a kaleidoscopical configuration if there is a coloring χ : X → k (i.e. a mapping of X onto a cardinal k) such that the ...
  • Kaluzhnin's representations of Sylow p-subgroups of automorphism groups of p-adic rooted trees 
    Bier, A.; Sushchansky, V. (Algebra and Discrete Mathematics, 2015)
    The paper concerns the Sylow p-subgroups of automorphism groups of level homogeneous rooted trees. We recall and summarize the results obtained by L.Kaluzhnin on the structure of Sylow p-subgroups of isometry groups of ...
  • Keller-Osserman a priori estimates and removability result for the anisotropic porous medium equation with absorption term 
    Shan, M.A. (Український математичний вісник, 2018)
    We obtain the removability result for quasilinear equations of the special form and prove a priori estimates of the Keller–Osserman type.
  • Kernel Functions for Difference Operators of Ruijsenaars Type and Their Applications 
    Komori, Y.; Noumi, M.; Shiraishi, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    A unified approach is given to kernel functions which intertwine Ruijsenaars difference operators of type A and of type BC. As an application of the trigonometric cases, new explicit formulas for Koornwinder polynomials ...
  • Kernel of a map of a shift along the orbits of continuous flows 
    Maksymenko, S.I. (Український математичний журнал, 2010)
    Let F:M × R → M be a continuous flow on a topological manifold M. For every subset V⊂M, we denote by P(V) the set of all continuous functions ξ:V→R such that F(x,ξ(x))=x for all x∈V. These functions vanish at nonperiodic ...
  • Kleinian singularities and algebras generated by elements that have given spectra and satisfy a scalar sum relation 
    Mellit, A. (Algebra and Discrete Mathematics, 2004)
    We consider the algebras eiΠλ (Q)ei , where Πλ (Q) is the deformed preprojective algebra of weight λ and i is some vertex of Q, in the case where Q is an extended Dynkin diagram and λ lies on the hyperplane orthogonal ...
  • Klein's Fundamental 2-Form of Second Kind for the Cab Curves 
    Suzuki, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    In this paper, we derive the exact formula of Klein's fundamental 2-form of second kind for the so-called Cab curves. The problem was initially solved by Klein in the 19th century for the hyper-elliptic curves, but little ...
  • Klein Topological Field Theories from Group Representations 
    Loktev, S.A.; Natanzon, S.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We show that any complex (respectively real) representation of finite group naturally generates a open-closed (respectively Klein) topological field theory over complex numbers. We relate the 1-point correlator for the ...
  • KP hierarchy and (1+1)-dimensional multicomponent integrable systems 
    Sidorenko, Yu.M. (Український математичний журнал, 1993)
    New types of reduction of the Kadomtsev-Petviashvili (KP) hierarchy are considered on the basis of Sato's approach. As a result, we obtain a new multicomponent nonlinear integrable system. Bi-Hamiltonian structures for the ...
  • KP Trigonometric Solitons and an Adelic Flag Manifold 
    Haine, L. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We show that the trigonometric solitons of the KP hierarchy enjoy a differential-difference bispectral property, which becomes transparent when translated on two suitable spaces of pairs of matrices satisfying certain rank ...
  • Krein Spaces in de Sitter Quantum Theories 
    Gazeau, J.P.; Siegl, P.; Youssef, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    Experimental evidences and theoretical motivations lead to consider the curved space-time relativity based on the de Sitter group SO0(1,4) or Sp(2,2) as an appealing substitute to the flat space-time Poincaré relativity. ...
  • KZ Characteristic Variety as the Zero Set of Classical Calogero-Moser Hamiltonians 
    Mukhin, E.; Tarasov, T.; Varchenko, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    We discuss a relation between the characteristic variety of the KZ equations and the zero set of the classical Calogero-Moser Hamiltonians.
