  • Exponential stabilization of longitudinal vibrations of an inhomogeneous beam 
    Gorain, G.C. (Нелінійні коливання, 2013)
    In this paper, we consider the longitudinal vibrations of an inhomogeneous beam with Kelvin – Voigt damping distributed along the length of the beam. We establish the uniform exponential decay of solution with an explicit ...
  • Exponent matrices and Frobenius rings 
    Dokuchaev, M.A.; Kasyanuk, M.V.; Khibina, M.A.; Kirichenko, V.V. (Algebra and Discrete Mathematics, 2014)
    We give a survey of results connecting the exponent matrices with Frobenius rings. In particular, we prove that for any parmutation σ ∈ Sn there exists a countable set of indecomposable Frobenius semidistributive rings Am ...
  • Exponent matrices and topological equivalence of maps 
    Fedorenko, V.; Kirichenko, V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2007)
    Conjugate classes of continuous maps of the interval [0,1] into itself, whose iterations form a finite group are described. For each of possible groups of iterations one to one correspondence between conjugate classes of ...
  • Extended Cosmologies 
    Capozziello, S.; De Laurentis, M.F.; Fatibene, L.; Ferraris, M.; Garruto, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    We shall discuss cosmological models in extended theories of gravitation. We shall define a surface, called the model surface, in the space of observable parameters which characterises families of theories. We also show ...
  • Extended G-vertex colored partition algebras as centralizer algebras of symmetric groups 
    Parvathi, M.; Kennedy, A.J. (Algebra and Discrete Mathematics, 2005)
    The Partition algebras Pk(x) have been defined in [M1] and [Jo]. We introduce a new class of algebras for every group G called “Extended G-Vertex Colored Partition Algebras," denoted by Pbk(x,G), which contain partition ...
  • Extended Hamiltonians, Coupling-Constant Metamorphosis and the Post-Winternitz System 
    Chanu, C.M.; Degiovanni, L.; Rastelli, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    The coupling-constant metamorphosis is applied to modified extended Hamiltonians and sufficient conditions are found in order that the transformed high-degree first integral of the transformed Hamiltonian is determined by ...
  • Extended Soliton Solutions in an Effective Action for SU(2) Yang-Mills Theory 
    Sawado, N.; Shiiki, N.; Tanaka, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    The Skyrme-Faddeev-Niemi (SFN) model which is an O(3) σ model in three dimensional space up to fourth-order in the first derivative is regarded as a low-energy effective theory of SU(2) Yang-Mills theory. One can show from ...
  • Extended star graphs 
    Gutierrez, M.; Tondato, S.B. (Algebra and Discrete Mathematics, 2016)
    Chordal graphs, which are intersection graph of subtrees of a tree, can be represented on trees. Some representation of a chordal graph often reduces the size of the data structure needed to store the graph, permitting the ...
  • Extended Stochastic Integral and Wick Calculus on Spaces of Regular Generalized Functions Connected with Gamma Measure 
    Kachanovskii, N.A. (Український математичний журнал, 2005)
    We introduce and study an extended stochastic integral, a Wick product, and Wick versions of holomorphic functions on Kondrat'ev-type spaces of regular generalized functions. These spaces are connected with the Gamma measure ...
  • Extended Tauberian Theorem for the weighted mean Method of Summability 
    Çanak, Ï.; Totur, Ü. (Український математичний журнал, 2013)
    We prove a new Tauberian-like theorem that establishes the slow oscillation of a real sequence u = (un) on the basis of the weighted mean summability of its generator sequence and some conditions.
  • Extended T-System of Type G₂ 
    Li, J.; Mukhin, E. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We prove a family of 3-term relations in the Grothendieck ring of the category of finite-dimensional modules over the affine quantum algebra of type G₂ extending the celebrated T-system relations of type G₂. We show that ...
  • Extension Fullness of the Categories of Gelfand-Zeitlin and Whittaker Modules 
    Coulembier, K.; Mazorchuk, V. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We prove that the categories of Gelfand-Zeitlin modules of g=gln and Whittaker modules associated with a semi-simple complex finite-dimensional algebra g are extension full in the category of all g-modules. This is used ...
  • Extension of holomorphic mappings for several moving hypersurfaces 
    Si Duc Quang (Український математичний журнал, 2012)
    We prove the big Picard theorem for holomorphic curves from a punctured disk into P ⁿ(C) with n + 2 hypersurfaces. We also prove a theorem on the extension of holomorphic mappings in several complex variables into a ...
  • Extension of Some Lions-Magenes Theorems 
    Murach, A.A. (2009)
    A general form of the Lions - Magenes theorems on solvability of an elliptic boundary-value problem in the spaces of nonregular distributions is proved. We find a general condition on the space of right-hand sides of the ...
  • Extension of the Poincaré Symmetry and Its Field Theoretical Implementation 
    Tanasa, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    We define a new algebraic extension of the Poincaré symmetry; this algebra is used to implement a field theoretical model. Free Lagrangians are explicitly constructed; several discussions regarding degrees of freedom, ...
  • Extension Phenomena for Holomorphic Geometric Structures 
    McKay, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    The most commonly encountered types of complex analytic G-structures and Cartan geometries cannot have singularities of complex codimension 2 or more.
  • Exterior Differential Systems for Yang-Mills Theories 
    Estabrook, F.B. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    Exterior differential systems are given, and their Cartan characters calculated, for Maxwell and SU(2)-Yang-Mills equations in dimensions from three to six.
  • External Ellipsoidal Harmonics for the Dunkl-Laplacian 
    Volkmer, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The paper introduces external ellipsoidal and external sphero-conal h-harmonics for the Dunkl-Laplacian. These external h-harmonics admit integral representations, and they are connected by a formula of Niven's type.
  • Extremal decomposition of multidimensional complex space for five domains 
    Zabolotni, i Y.; Denega, I. (Український математичний вісник, 2018)
    The paper is devoted to one open extremal problem in the geometric function theory of complex variables associated with estimates of a functional defined on the systems of non-overlapping domains. We consider the problem ...
  • Extremal quasiconformality vs bounded rational approximation 
    Krushkal, S.L. (Український математичний вісник, 2019)
    We show that, on most of the hyperbolic simply connected domains, the weighty bounded rational approximation in a natural sup norm is possible only for a very sparse set of holomorphic functions (in contrast to the integral ...
