  • 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 ...
  • 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 ...
  • 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 ...
  • 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.
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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.
  • Иващук, Я.Г. (Український математичний журнал, 1993)
    k-ужи являются обобщением полиномов, наименее уклоняющихся or нуля при наличии к свя­зей. Доказано существование и единственность k-ужей в интерполяционных классах конечного порядка и их непрерывная дифференцируемость по ...
  • Орлов, И.В. (Український математичний вісник, 2006)
    Исследуются свойства компактных экстремумов функционалов в локально выпуклом пространстве, в частности, интегральных функционалов. Рассмотрены примеры.
  • Ломако, Т.В. (Український математичний журнал, 2011)
    Доведено теореми збiжностi та компактностi класiв регулярних розв’язкiв вироджених рiвнянь Бельтрамi з обмеженнями iнтегрального типу на дилатацiю.
  • Sharko, V.V. (Український математичний журнал, 2007)
    Вивчаються гомотопічні інваріанти вільних коланцюгових та гільбертових комплексів. Ці L²-інваріанти застосовуються при обчисленні точних значень мінімальних чисел замкнених орбіт фіксованих індексів несингулярних потоків ...
  • Dinesh, T.; Ramakrishnan, T.V. (Algebra and Discrete Mathematics, 2013)
    The concept of graph structure was introduced by E. Sampathkumar in 'Generalised Graph Structures', Bull. Kerala Math. Assoc., Vol 3, No.2, Dec 2006, 65-123. Based on the works of Brouwer, Doob and Stewart, R.H. Jeurissen ...
  • Méndez-Fragoso, R.; Ley-Koo, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    Three sets of ladder operators in spheroconal coordinates and their respective actions on Lamé spheroconal harmonic polynomials are presented in this article. The polynomials are common eigenfunctions of the square of the ...
  • Ley-Koo, E.; Sun, G.-H. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    We report the identification and construction of raising and lowering operators for the complete eigenfunctions of isotropic harmonic oscillators confined by dihedral angles, in circular cylindrical and spherical coordinates; ...
