  • Fulling, S.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Quantum vacuum energy (Casimir energy) is reviewed for a mathematical audience as a topic in spectral theory. Then some one-dimensional systems are solved exactly, in terms of closed classical paths and periodic orbits. ...
  • Komarov, I.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    The paper is dedicated to the memory of prominent theoretical physicist and mathematician Dr. Vadim Kuznetsov who worked, in particular, in the fields of the nonlinear dynamics, separation of variables, integrability theory, ...
  • Laurincikas, A. (Algebra and Discrete Mathematics, 2006)
    A joint limit theorem on the complex plane for a new class of general Dirichlet series is proved.
  • Wu, Chun (Український математичний журнал, 2014)
    We study the uniqueness of entire functions sharing a nonzero value and obtain some results improving the results obtained by Fang, J. F. Chen, X.Y. Zhang and W. C. Lin, et al.
  • Vu Hoai An; Ha Huy Khoai (Український математичний журнал, 2012)
    We discuss the value-sharing problem, versions of the Hayman conjecture, and the uniqueness problem for p-adic meromorphic functions, as well as their difference operators and difference polynomials.
  • Nguyen Van Dao; Nguyen Van Dinh; Tran Kim Chi (2007)
    Досліджено вплив параметричного та зовнішнього збурень на систему Ван дер Поля. Розглянуто випадки, коли дана система містить малий параметр і є кназілінійною та загальний випадок (без припущення про мализну нелінійних ...
  • Belopolskaya, Ya. (Український математичний вісник, 2005)
    We construct diffusion processes associated with nonlinear parabolic equations and study their behavior as the viscosity (diffusion) coefficients go to zero. It allows to construct regularizations for solutions to hyperbolic ...
  • Desiateryk, O.O.; Ganyushkin, O.G. (Algebra and Discrete Mathematics, 2018)
    In this paper we consider the ordered by inclusion lattice Part(M) of all partitions of a countable set M. The lattice Part(M) is a semigroup with respect to the operation Λ which maps two partitions to their greatest ...
  • Palese, M.; Rossi, O.; Winterroth, E.; Musilová, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    This paper is a review containing new original results on the finite order variational sequence and its different representations with emphasis on applications in the theory of variational symmetries and conservation laws ...
  • Sharapov, A.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    Using the concept of variational tricomplex endowed with a presymplectic structure, we formulate the general notion of symmetry. We show that each generalized symmetry of a gauge system gives rise to a sequence of conservation ...
  • Tadumadze, T. (Нелінійні коливання, 2014)
    Variation formulas for solution are proved for a nonlinear differential equation with constant delays. In this work, the essential novelty is an effect of delay perturbation in the variation formulas. The mixed initial ...
  • Carlson, J.; Green, M.; Griffiths, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    This paper is a survey of the subject of variations of Hodge structure (VHS) considered as exterior differential systems (EDS). We review developments over the last twenty-six years, with an emphasis on some key examples. ...
  • Grau, J.-M.; Oller-Marcén, A.M. (Український математичний журнал, 2015)
  • Mawhin, J. (Український математичний журнал, 2013)
    We give rather elementary topological proofs of some generalizations of fixed-point theorems in Rⁿ due to Pireddu-Zanolin and Zgliczynski, which are useful in various questions related to ordinary differential equations.
  • Kashuba, I. (Algebra and Discrete Mathematics, 2006)
    The variety J orn of Jordan unitary algebra structures on k n , k an algebraically closed field with char k 6= 2 , is studied, as well as infinitesimal deformations of Jordan algebras. Also we establish the list of ...
  • Jardim, M.; Prata, D.M. (Algebra and Discrete Mathematics, 2015)
    We present equivalences between certain categories of vector bundles on projective varieties, namely cokernel bundles, Steiner bundles, syzygy bundles, and monads, and full subcategories of representations of certain ...
  • Drozd, Y.A.; Voloshyn, D.E. (Український математичний журнал, 2012)
    We describe vector bundles over a class of noncommutative curves, namely, over noncommutative nodal curves of string type and of almost string type. We also prove that, in other cases, the classification of vector bundles ...
  • Airault, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We obtain the Kirillov vector fields on the set of functions f univalent inside the unit disk, in terms of the Faber polynomials of 1/f(1/z). Our construction relies on the generating function for Faber polynomials.
  • Dunkl, C.F. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The space of polynomials in two real variables with values in a 2-dimensional irreducible module of a dihedral group is studied as a standard module for Dunkl operators. The one-parameter case is considered (omitting the ...
  • Dunkl, C.F.; Luque, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    Vector-valued Jack polynomials associated to the symmetric group SN are polynomials with multiplicities in an irreducible module of SN and which are simultaneous eigenfunctions of the Cherednik-Dunkl operators with some ...
