  • 1-D Schrodinger operators with local interactions on a discrete set with unbounded potentia 
    Ananieva, A.Yu. (Український математичний вісник, 2016)
    We study spectral properties of the One-dimensional Schrodinger operators.
  • About one extremal problem for open sets and partially non-overlapping domains 
    Targonskii, A.L.; Targonskaya, I.I.; Vashenko, K. (Український математичний вісник, 2019)
    Sharp estimates of a product of the inner radii for pairwise disjoint domains are obtained. In particular, we solve an extremal problem in the case of any finite number of free poles on the rays.
  • About one extremal problem for projections of the points on unit circle 
    Targonskii, A.L. (Український математичний вісник, 2018)
    Sharp estimates of a product of inner radii for pairwise disjoint domains are obtained. In particular, the extremal problem in the case of any finite number of free poles at the points on rays is solved.

  • A class of periodic integral equations with numerical solving by a fully discrete projection method 
    Solodky, S.G.; Semenova, E.V. (Український математичний вісник, 2014)
    For a class of integral periodic equations of the first kind the problem of stable approximate solving is considered. The error estimates in the metric of Sobolev spaces for a fully discrete projection method with two ...
  • Adapted statistical experiments 
    Koroliouk, D.V. (Український математичний вісник, 2016)
    We study statistical experiments with random change of time, which transforms a discrete stochastic basis in a continuous one. The adapted stochastic experiments are studied in continuous stochastic basis in the series ...
  • Adaptive scheme of discretization for one semiiterative method in solving ill-posed problems 
    Solodky, S.G.; Volynets, E.A. (Український математичний вісник, 2010)
    In the paper we consider a new algorithm to solving linear ill-posed problem with operators of finite smoothness. The algorithm uses one semiiterative method for the regularization of original problem in combination with ...
  • A functional model associated with a generalized Nevanlinna pair 
    Neiman, E. (Український математичний вісник, 2010)
    Let L be a Hilbert space and let H be a Pontryagin space. For every selfadjoint linear relation à in H⊕L the pair {I+λψ(λ), ψ(λ)}, where ψ(λ) is the compressed resolvent of Ã, is a normalized generalized Nevanlinna pair. ...
  • Analytic in an unit ball functions of bounded L-index in joint variables 
    Bandura, A.I.; Skaskiv, O.B. (Український математичний вісник, 2017)
    A concept of boundedness of the L-index in joint variables (see in Bandura A. I., Bordulyak M. T., Skaskiv O. B. Sufficient conditions of boundedness of L-index in joint variables, Mat. Stud. 45 (2016), 12–26) is generalized ...
  • An extremal problem for the non-overlapping domains 
    Targonskii, A. (Український математичний вісник, 2017)
    Sharp estimates of product of inner radii for pairwise disjoint domains are obtained. In particular, we solve an extremal problem in the case of arbitrary finite number of free poles on the system points on the rays.
  • An operator approach to indefinite Stieltjes moment problem 
    Derkach, V.A.; Kovalyov, I.M. (Український математичний вісник, 2017)
    In the present paper we solve the indefinite Stieltjes moment problem MPkκ(s) within the M.G. Krein theory of u-resolvent matrices applied to a Pontryagin space symmetric operator A[0,N] generated by J[0,N]. The u-resolvent ...
  • Application of the Thomas precession to the deformations of a rotating disk 
    Celakoska, E.G.; Trecevski, K.; Balan, V. (Український математичний вісник, 2009)
    Within the framework of Special Relativity, the recent paper [1] describes the shrinking determined by the rotation of a planar disk, and an apparent paradox emerging from the anisotropic outcoming contraction. In this ...
  • Approximate controllability of the wave equation with mixed boundary conditions 
    Pestov, L.; Strelnikov, D. (Український математичний вісник, 2018)
    We consider initial boundary-value problem for acoustic equation in the time space cylinder Ω×(0, 2T) with unknown variable speed of sound, zero initial data, and mixed boundary conditions. We assume that (Neumann) controls ...
  • Approximative properties of the Weierstrass integrals on the classes WrβHα 
    Grabova, U.Z.; Kal'chuk, I.V.; Stepaniuk, T.A. (Український математичний вісник, 2017)
    The work focuses on the solution of a problem of approximation theory. The task is to investigate approximative properties of the Weierstrass integrals on the classes WrβHα. We obtain asymptotic equalities for the upper ...
