  • Word length in symmetrized presentations of Thompson’s group F 
    Horak, M.; Johnson, A.; Stonesifer, A. (Algebra and Discrete Mathematics, 2012)
    Thompson's groups F, T and Z were introduced by Richard Thompson in the 1960's in connection with questions in logic. They have since found applications in many areas of mathematics including algebra, logic and topology, ...
  • Wqˡ-regularity of solutions to systems of partial differential equations 
    Kopylov, A.P. (Нелинейные граничные задачи, 2004)
    We obtain a solution, in a sense final from the standpoint of the theory of Sobolev spaces, to the problem of Wqˡ-regularity of solutions to a system of (generally) nonlinear partial differential equations in the case where ...
  • Wreath product of Lie algebras and Lie algebras associated with Sylow p-subgroups of finite symmetric groups 
    Sushchansky, V.I.; Netreba, N.V. (Algebra and Discrete Mathematics, 2005)
    We define a wreath product of a Lie algebra L with the one-dimensional Lie algebra L1 over Fp and determine some properties of this wreath product. We prove that the Lie algebra associated with the Sylow p-subgroup of ...
  • Wreath product of metric spaces 
    Oliynyk, B. (Algebra and Discrete Mathematics, 2007)
    This paper describes a new construction of wreath product of metric spaces. The group of isometries of the wreath product of metric spaces is calculated.
  • X-перестановочные максимальные подгруппы силовских подгрупп конечных групп 
    Го Вэньбинь; Шам, К.П.; Скиба, А.Н. (Український математичний журнал, 2006)
    Вивчаються скінченш групи, у яких максимальні підгрупи силовських підгруп є переставними з максимальними пiдгрупами.
  • Yang-Baxter Maps from the Discrete BKP Equation 
    Kakei, S.; Nimmo, J; Willox, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    We construct rational and piecewise-linear Yang–Baxter maps for a general N-reduction of the discrete BKP equation.
  • Yangian of the Strange Lie Superalgebra of Qn₋₁ Type, Drinfel'd Approach 
    Stukopin, V. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    The Yangian of the strange Lie superalgebras in Drinfel'd realization is defined. The current system generators and defining relations are described.
  • Yetter–Drinfel’d Hopf algebras on basic cycle 
    Yanhua Wang; Guohua Liu (Український математичний журнал, 2014)
    A class of Yetter–Drinfel’d Hopf algebras on basic cycle is constructed.
  • Yuriy Drozd (dedicated to 75th Birthday) 
    Автор відсутній (Algebra and Discrete Mathematics, 2019)
    On October 15, 2019 an outstanding Ukrainian mathematician, one of the founders of Kyiv algebraic school Yuriy Drozd celebrated his 75th birthday.
  • Zamolodchikov Tetrahedral Equation and Higher Hamiltonians of 2d Quantum Integrable Systems 
    Talalaev, D.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The main aim of this work is to develop a method of constructing higher Hamiltonians of quantum integrable systems associated with the solution of the Zamolodchikov tetrahedral equation. As opposed to the result of V.V. ...
  • Zero Action on Perfect Crystals for Uq(G₂⁽¹⁾) 
    Misra, K.C.; Mohamad, M.; Okado, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The actions of 0-Kashiwara operators on the Uq'(GG₂⁽¹⁾)-crystal Bl in [Yamane S., J. Algebra 210 (1998), 440-486] are made explicit by using a similarity technique from that of a Uq'(D₄⁽³⁾)-crystal. It is shown that {Bl}l ...
  • Zero Range Process and Multi-Dimensional Random Walks 
    Bogoliubov, N.M.; Malyshev, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The special limit of the totally asymmetric zero range process of the low-dimensional non-equilibrium statistical mechanics described by the non-Hermitian Hamiltonian is considered. The calculation of the conditional ...
  • Zeros of Quasi-Orthogonal Jacobi Polynomials 
    Driver, K.; Jordaan, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We consider interlacing properties satisfied by the zeros of Jacobi polynomials in quasi-orthogonal sequences characterised by α>−1, −2<β<−1. We give necessary and sufficient conditions under which a conjecture by Askey, ...
  • Zero-sum subsets of decomposable sets in Abelian groups 
    Banakh, T.; Ravsky, A. (Algebra and Discrete Mathematics, 2020)
    A subset D of an abelian group is decomposable if ∅ ≠ D ⊂ D + D. In the paper we give partial answers to an open problem asking whether every finite decomposable subset D of an abelian group contains a non-empty subset ...
  • Zeta Functions of Monomial Deformations of Delsarte Hypersurfaces 
    Kloosterman, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    Let Xλ and X′λ be monomial deformations of two Delsarte hypersurfaces in weighted projective spaces. In this paper we give a sufficient condition so that their zeta functions have a common factor. This generalises results ...
  • Zhedanov's Algebra AW(3) and the Double Affine Hecke Algebra in the Rank One Case. II. The Spherical Subalgebra 
    Koornwinder, T.H. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    This paper builds on the previous paper by the author, where a relationship between Zhedanov's algebra AW(3) and the double affine Hecke algebra (DAHA) corresponding to the Askey-Wilson polynomials was established. It is ...
  • Z-, R- и H-сечения полугруппы сильных эндоморфизмов неориентированных графов
