  • Andreev-Korkin Identity, Saigo Fractional Integration Operator and LipL(α) Functions 
    Jankov, D.; Pogány, T.K. (Журнал математической физики, анализа, геометрии, 2012)
    The Andreev-Korkin identity for the Chebyshev functional is treated by Holder inequality, when the functional consists of LipL(α) functions. The derived upper bound is applied to the so-called Chebyshev-Saigo functional, ...
  • An Example of Bianchi Transformation in E⁴ 
    Gorkavyy, V. (Журнал математической физики, анализа, геометрии, 2012)
    We describe a particular class of pseudo-spherical surfaces in E⁴ which admit Bianchi transformations
  • Antipodal Polygons and Their Group Properties 
    Medianik, A.I. (Журнал математической физики, анализа, геометрии, 2012)
    We study the groups of transformations which transform antipodal polygons into antipodal ones as well as their order and the number of equivalence classes of n-gons inscribed into the regular (2n - 1)-gon.
  • A Symmetric Model of Viscous Relaxing Fluid. An Evolution Problem 
    Zakora, D. (Журнал математической физики, анализа, геометрии, 2012)
    An evolution problem on small motions of the viscous rotating relaxing fluid in a bounded domain is studied. The problem is reduced to the Cauchy problem for the first-order integro-differential equation in a Hilbert space. ...
  • Characterization of Hyperbolic Cylinders in a Lorentzian Space Form 
    Shu, Sh.; Han, Annie Yi (Журнал математической физики, анализа, геометрии, 2012)
    We give a characterization of the n-dimensional (n ≥ 3) hyperbolic cylinders in a Lorentzian space form. We show that the hyperbolic cylinders are the only complete space-like hypersurfaces in an (n + 1)-dimensional ...
  • Elementary Solutions of the Bernstein Problem on Two Intervals 
    Pausinger, F. (Журнал математической физики, анализа, геометрии, 2012)
    First we note that the best polynomial approximation to jxj on the set, which consists of an interval on the positive half-axis and a point on the negative half-axis, can be given by means of the classical Chebyshev ...
  • General Boundary Value Problem for the Third Order Linear Differential Equation of Composite Type 
    Gharehgheshlaghi, A.D.; Aliyev, N. (Журнал математической физики, анализа, геометрии, 2012)
    The boundary value problem is considered for the linear two-dimensional integro-di®erential loaded third order equation of composite type with nonlocal terms in the boundary conditions. The principal part of the equation ...
  • Good Measures on Locally Compact Cantor Sets 
    Karpel, O.M. (Журнал математической физики, анализа, геометрии, 2012)
    We study the set M(X) of full non-atomic Borel measures μ on a non-compact locally compact Cantor set X. The set Mμ = {x is in X : for any compact open set U (x is in U) we have μ(U) = ∞} is called defective. μ is non-defective ...
  • Homogenization of Spectral Problem on Small-Periodic Networks 
    Krylova, A.S.; Sandrakov, G.V. (Журнал математической физики, анализа, геометрии, 2012)
    The homogenization of a spectral problem on small-periodic networks with periodic boundary conditions is considered. Asymptotic expansions for eigenfunctions and corresponding eigenvalues on the network are con- structed. ...
  • Hyers-Ulam Stability of Ternary (σ, t, ξ)-Derivations on C*-Ternary Algebras 
    Gordji, M.E.; Farrokhzad, R.; Hosseinioun, S.A.R. (Журнал математической физики, анализа, геометрии, 2012)
  • On Affine Immersions with Flat Connections 
    Shugailo, O.O. (Журнал математической физики, анализа, геометрии, 2012)
    In this paper, the multidimensional affine immersions with °flat connections of maximal pointwise codimension are studied. The estimates on the dimensions of kernel and the image of the shape (Weingarten) operator and the ...
  • On Geodesics of Tangent Bundle with Fiberwise Deformed Sasaki Metric over Kählerian Manifold 
    Yampolsky, A. (Журнал математической физики, анализа, геометрии, 2012)
    We propose a fiber-wise deformation of the Sasaki metric on slashed and unit tangent bundles over the Kalerian manifold based on the Berger deformation of metric on a unit sphere. The geodesics of this metric have different ...
  • On Ideal Amenability of Banach Algebras 
    Jabbari, A. (Журнал математической физики, анализа, геометрии, 2012)
    Let A be a Banach algebra. The Banach algebra A is said to be ideally amenable if every continuous derivation from A into I¤ is inner, where I is a two-sided ideal of A. In this paper, we consider the ideal amenability of ...
  • On the Neumann Boundary Controllability for the Non-Homogeneous String on a Half-Axis 
    Khalina, K.S. (Журнал математической физики, анализа, геометрии, 2012)
    In the paper, the equation of a vibrating non-homogeneous string, whose potential is not equal to a constant, is considered on a half-axis. The Neumann control of the class L∞ is considered at a point x = 0. The control ...
  • On the Universal Models of Commutative Systems of Linear Operators 
    Hatamleh, R.; Zolotarev, V.A. (Журнал математической физики, анализа, геометрии, 2012)
  • Some Properties Concerning Curvature Tensors of Eight-Dimensional Walker Manifolds 
    Iscan, M.; Gezer, A.; Salimov, A. (Журнал математической физики, анализа, геометрии, 2012)
    The main purpose of the present paper is to study conditions for the eight-dimensional Walker manifolds which admit a field of parallel null 4-planes to be Einsteinian, Osserman, or locally conformally flat.
  • Spectral Mapping Theorem for the Davies-Helffer-Sjöstrand Functional Calculus 
    Claire, N.S. (Журнал математической физики, анализа, геометрии, 2012)
    We give a direct non-abstract proof of the spectral mapping theorem for the Davies–Helffer–Sjöstrand functional calculus for linear operators on Banach spaces with real spectra and consequently give a new non-abstract ...
  • Spectral Problem Generated by the Equation of Smooth String with Piece-Wise Constant Friction 
    Kobyakova, L. (Журнал математической физики, анализа, геометрии, 2012)
    In the paper, the spectral problem generated by the Sturm-Liouville equation -y'' + q(x)y = (λ² - ip(x)λ)y, where q(x) is a real L₂(0, a)-function and p(x) is a peace-wise constant, is considered with the Dirichlet boundary ...
  • Step-Initial Function to the MKdV Equation: Hyper-Elliptic Long-Time Asymptotics of the Solution 
    Kotlyarov, V.; Minakov, A. (Журнал математической физики, анализа, геометрии, 2012)
    The modified Korteveg{de Vries equation on the line is considered. The initial function is a discontinuous and piece-wise constant step function, i.e. q(x, 0) = cr for x ≥ 0 and q(x, 0) = cl for x < 0, where cl, cr are ...
  • The Truncated Fourier Operator. General Results 
    Katsnelson, V.; Machluf, R. (Журнал математической физики, анализа, геометрии, 2012)
    Let F be the one dimensional Fourier-Plancherel operator and E be a subset of the real axis. The truncated Fourier operator is the operator FE of the form FE = PEFPE, where (PEx)(t) = 1IE(t)x(t), and 1IE(t) is the indicator ...
