  • Tableau Formulas for One-Row Macdonald Polynomials of Types Cn and Dn 
    Feigin, B.; Hoshino, A.; Noumi, M.; Shibahara, J.; Shiraishi, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We present explicit formulas for the Macdonald polynomials of types Cn and Dn in the one-row case. In view of the combinatorial structure, we call them ''tableau formulas''. For the construction of the tableau formulas, ...
  • Tame and wild subspace problems 
    Gabriel, P.; Nazarova, L.A.; Roiter, A.V.; Sergeichuck, V.V.; Vossieck, D. (Український математичний журнал, 1993)
  • Tangent spaces to metric spaces and to their subspaces 
    Dovgoshey, O.A. (2008)
    We investigate tangent spaces and metric space valued derivatives at points of a general metric spaces. The conditions under which two different subspaces of the metric space have isometric tangent spaces in the common ...
  • Teichmüller Theory of Bordered Surfaces 
    Chekhov, L.O. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We propose the graph description of Teichmüller theory of surfaces with marked points on boundary components (bordered surfaces). Introducing new parameters, we formulate this theory in terms of hyperbolic geometry. We can ...
  • Ternary Hopf algebras 
    Zekovic, B. (Algebra and Discrete Mathematics, 2005)
    In this paper we introduce the notion of a ternary Hopf algebra and prove that it can be embedded into a universal enveloping Hopf algebra.
  • t-Generalized Supplemented Modules 
    Koşar, B.; Nebiyev, C. (Український математичний журнал, 2015)
    In the present paper, t-generalized supplemented modules are defined starting from the generalized ⨁-supplemented modules. In addition, we present examples separating the t-generalized supplemented modules, supplemented ...
  • The 12-th Scientific Session of the Mathematical Commission of the T. H. Shevchenko Scientific Society 
    Samoilenko, A.M.; Prytula, M.M. (Нелінійні коливання, 2001)
    A session of the mathematical commission of the T.H. Shevchenko Scientific Society (SSS) was held on March 16 – 17, 2001 at the I. Franko L’viv National University. The session was organized both by the mathematical ...
  • The 2-Transitive Transplantable Isospectral Drums 
    Schillewaert, J.; Thas, K. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    For Riemannian manifolds there are several examples which are isospectral but not isometric, see e.g. J. Milnor [Proc. Nat. Acad. Sci. USA 51 (1964), 542]; in the present paper, we investigate pairs of domains in R² which ...
  • The 6 Vertex Model and Schubert Polynomials 
    Lascoux, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    We enumerate staircases with fixed left and right columns. These objects correspond to ice-configurations, or alternating sign matrices, with fixed top and bottom parts. The resulting partition functions are equal, up to ...
  • The action of Sylow 2-subgroups of symmetric groups on the set of bases and the problem of isomorphism of their Cayley graphs 
    Pawlik, B.T. (Algebra and Discrete Mathematics, 2016)
    Base (minimal generating set) of the Sylow 2-subgroup of S₂n is called diagonal if every element of this set acts non-trivially only on one coordinate, and different elements act on different coordinates. The Sylow 2-subgroup ...
  • The Algebra of a q-Analogue of Multiple Harmonic Series 
    Takeyama, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We introduce an algebra which describes the multiplication structure of a family of q-series containing a q-analogue of multiple zeta values. The double shuffle relations are formulated in our framework. They contain a ...
  • The algorithms that recognize Milnor laws and properties of these laws 
    Tomaszewski, W. (Algebra and Discrete Mathematics, 2014)
    We consider several equivalent definitions of the so-called Milnor laws (or Milnor identities) that is the laws which are not satisfied in ApA varieties. The purpose of this article is to provide algorithms that allow us ...
  • The Analytic Continuation of the Lippmann-Schwinger Eigenfunctions, and Antiunitary Symmetries 
    de la Madrid, R. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    We review the way to analytically continue the Lippmann-Schwinger bras and kets into the complex plane. We will see that a naive analytic continuation leads to nonsensical results in resonance theory, and we will explain ...
  • The application of the intersect index to quasilinear eigenfunction problems 
    Dymarsky, Ya.M. (Нелинейные граничные задачи, 1999)
    First time the intersect index was applied to non-linear problems in L. Lusternick's research. This direction is investigating at voronezh school now [1,2]. Small eigenfunctions and its global branches was considered by ...
  • The application of variational methods to some static contact problems for pliant shells of rotation 
    Trotsenko, V. A. (Нелінійні коливання, 1999)
    We propose a method for finding the finite deformations of hyperelastic domal shells of rotation due to hydrostatic load. The problem is considered under the condition that the deformed surface of the shell enters the ...
  • The Asymptotic Expansion of Kummer Functions for Large Values of the α-Parameter, and Remarks on a Paper by Olver 
    Volkmer, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    It is shown that a known asymptotic expansion of the Kummer function U(a,b,z) as a tends to infinity is valid for z on the full Riemann surface of the logarithm. A corresponding result is also proved in a more general ...
  • The behavior of solutions of the mixed boundary value problem for a linear second-order elliptic equation in a neighbourhood of intersecting edges 
    Plesha, M. (2008)
    In this paper we deals with the mixed boundary value problem for secondorder elliptic equations in a polyhedral domain. We obtain exact estimates for solutions of the problem in a neighbourhood of an vertex. A special ...
  • The Beltrami equation and ring homeomorphisms 
    Ryazanov, V.; Srebro, U.; Yakubov, E. (Український математичний вісник, 2007)
    With the aid of results by Gehring, we introduce and study plane ring Q-homeomorphisms. This study is then applied in deriving general principles on the existence and uniqueness of homeomorphic ACL solutions to the Beltrami ...
  • The Beltrami equations and lower Q-homeomorphisms 
    Kovtonyuk, D.A.; Petkov, I.V.; Ryazanov, V.I. (Труды Института прикладной математики и механики, 2010)
    In this article it is shown that each homeomorphic W1,1loc solution to the Beltrami equation ∂f = μ∂f is the so-called lower Q-homeomorphism with Q(z) = Kμ(z) where Kμ(z) is dilatation quotient of this equation. It is ...
  • The Beltrami equations and prime ends 
    Gutlyanskii, V.Y.; Ryazanov, V.I.; Yakubov, E. (Український математичний вісник, 2015)
    We first study the boundary behavior of ring Q-homeomorphisms in terms of Carath´eodory’s prime ends and then give criteria to the solvability of the Dirichlet problem for the degenerate Beltrami equation ∂f = μ∂f in ...
