  • Modified Sobolev Spaces in Controllability Problems for the Wave Equation on a Half-Plane 
    Fardigola, L.V. (Журнал математической физики, анализа, геометрии, 2015)
    The 2-d wave equation wtt = Δw, t belongs (0, T), on the half-plane x1 > 0 controlled by the Neumann boundary condition wx1(0, x2, t) = δ(x2)u(t) is considered in Sobolev spaces, where T > 0 is a constant and u  L∞(0, T) ...
  • Note on Lieb-Thirring Type Inequalities for a Complex Perturbation of Fractional Laplacian 
    Dubuisson, C. (Журнал математической физики, анализа, геометрии, 2015)
    For s > 0, let H0 = (-∆)s be the fractional Laplacian. In this paper, we obtain Lieb-Thirring type inequalities for the fractional Schrödinger operator defined as H = H0 + V , where V ∈ Lp(ℝd), p ≥ 1, d ≥ 1, is a complex-valued ...
  • On a Limiting Distribution of Singular Values of Random Band Matrices 
    Lytova, A.; Pastur, L. (Журнал математической физики, анализа, геометрии, 2015)
    An equation is obtained for the Stieltjes transform of the normalized distribution of singular values of non-symmetric band random matrices in the limit when the band width and rank of the matrix simultaneously tend to ...
  • On Integration of One Class of Systems of Lax-Type Equations 
    Lunyov, A.A.; Oliynyk, E.V. (Журнал математической физики, анализа, геометрии, 2015)
    A nonlinear system of Lax-type equations is studied. The system is the basis of the construction of triangular models for commutative systems of linear non-selfadjoint bounded operators. Some of its solutions for n = 4 are ...
  • On Model Representations of Non-Selfadjoint Operators with Infinitely Dimensional Imaginary Component 
    Hatamleh, R.; Zolotarev, V.A. (Журнал математической физики, анализа, геометрии, 2015)
    For an entirely non-selfadjoint operator with spectrum at zero, the imaginary component of which has an absolutely continuous spectrum (not necessarily dissipative and having lacunas in the spectrum), triangular and ...
  • On Stability and Stabilization of Perturbed Time Scale Systems with Gronwall Inequalities 
    Ben Nasser, B.; Boukerrioua, K.; Hammami, M.A. (Журнал математической физики, анализа, геометрии, 2015)
    In the paper, new nonlinear time scale integral inequalities are given. By means of the explicit integral bounds, we derive suffcient conditions for the uniform asymptotic stability of perturbed systems on time scales. In ...
  • On the Growth of the Cauchy-Szegő Transform in the Unit Ball 
    Chyzhykov, I.; Voitovych, M. (Журнал математической физики, анализа, геометрии, 2015)
    The growth of analytic and harmonic functions in the unit ball Bn represented by the Cauchy-Stieltjes or Poisson-Stieltjes integral is studied. A description of the growth is given in terms of smoothness of the Stieltjes measure.
  • On the Jost Solutions for a Class of Schrödinger Equations with Piecewise Constant Coefficients 
    Nabiev, A.A.; Mamedov, Kh.R. (Журнал математической физики, анализа, геометрии, 2015)
    In this paper, the new integral representations for the Jost solutions of the one-dimensional Schrödinger equation with the piecewise-constant leading coe±cient are obtained. The connections, obtained between the kernel ...
  • Properties of Modified Riemannian Extensions 
    Gezer, A.; Bilen, L.; Cakmak, A. (Журнал математической физики, анализа, геометрии, 2015)
    Let M be an n-dimensional differentiable manifold with a symmetric connection ∇ and T*M be its cotangent bundle. In this paper, we study some properties of the modified Riemannian extension ğ∇, c on T*M defined by means ...
  • Some Sharp Estimates for Convex Hypersurfaces of Pinched Normal Curvature 
    Drach, K. (Журнал математической физики, анализа, геометрии, 2015)
    For a convex domain D bounded by the hypersurface ∂D in a space of constant curvature we give sharp bounds on the width R - r of a spherical shell with radii R and r that can enclose ∂D, provided that normal curvatures of ...
  • Subdiagrams of Bratteli Diagrams Supporting Finite Invariant Measures 
    Bezuglyi, S.; Karpel, O.; Kwiatkowski, J. (Журнал математической физики, анализа, геометрии, 2015)
    We study finite measures on Bratteli diagrams invariant with respect to the tail equivalence relation. Amongst the proved results on the finiteness of measure extension, we characterize the vertices of a Bratteli diagram ...
  • The Singular Limit of the Dissipative Zakharov System 
    Shcherbina, A.S. (Журнал математической физики, анализа, геометрии, 2015)
    The dissipative Zakharov system which models the propagation of Langmuir waves in plasmas is considered on the interval [0, L]. We are interested in the case of large ion acoustic speed λ. After the formal limiting transition ...
  • Various Types of Convergence of Sequences of Subharmonic Functions 
    Nguyen Van Quynh (Журнал математической физики, анализа, геометрии, 2015)
    Let υn(x) be a sequence of subharmonic functions in a domain G is subset of Rm. The conditions under which the convergence of υn(x), as a sequence of generalized functions, implies its convergence in the Lebesgue spaces ...
