  • Factorization of generalized γ-generating matrices 
    Sukhorukova, O. (Український математичний вісник, 2017)
    The class of γ–generating matrices and its subclasses of regular and singular γ–generating matrices were introduced by D. Z. Arov in [8], where it was shown that every γ-generating matrix admits an essentially unique ...
  • Finite spaces pretangent to metric spaces at infinity 
    Bilet V., V.; Dovgoshey O., O. (Український математичний вісник, 2018)
  • Fundamental solutions of boundary problems and resolvents of differential operators 
    Mogilevskii, V. (Український математичний вісник, 2009)
    The main objects of our considerations are differential operators generated by a formally selfadjoint differential expression of an even order. The coefficients of this expression are operator valued functions defined on ...
  • Fuzzy strongly pre-irresolute functions 
    Gowrisankar, N.; Rajesh, N. (Український математичний вісник, 2010)
    In this paper, we have introduced and studied a new class of fuzzy irresolute functions, called fuzzy strongly pre-irresolute functions by using fuzzy preopen sets.
  • General Beltrami equations and BMO 
    Bojarski, B.V.; Gutlyanskii, V.V.; Ryazanov, V.I. (Український математичний вісник, 2008)
    We study the Beltrami equations ∂f = μ(z)∂f + ν(z)∂f under the assumption that the coefficients μ, ν satisfy the inequality |μ| + |ν| < 1 almost everywhere. Sufficient conditions for the existence of homeomorphic ACL ...
  • Generalized integral theorems for the quaternionic G-monogenic mappings 
    Kuzmenko, T.S.; Shpakivskyi, V.S. (Український математичний вісник, 2016)
    For G-monogenic mappings taking values in the algebra of complex quaternions, we generalize some analogues of classical integral theorems of the holomorphic function theory of complex variable (the surface and curvilinear ...
  • Global asymptotic stability of a higher order difference equation 
    Hamza, A.E.; Khalaf-Allah, R. (Український математичний вісник, 2007)
    The aim of this work is to investigate the global stability, periodic nature, oscillation and boundedness of solutions of the difference equation.
  • Global Mandelbrot transformation for Maslov tunnel pseudodifferential equations 
    Danilov, V.G. (Український математичний вісник, 2008)
    We construct the global in time Mandelbrot transformation relating the solution of the transport equation at nonsingular points for the tunnel in the sense of Maslov LPDE to the global generalized deltashock wave type ...
  • Group Classification of Systems of Non-Linear Reaction-Diffusion Equations 
    Nikitin, A.G. (Український математичний вісник, 2005)
    The completed group classification of systems of two coupled nonlinear reaction-diffusion equation with general diffusion matrix is carried out. The simple and convenient method for deduction and solution of classifying ...
  • Growth and representation of analytic and harmonic functions in the unit disc 
    Chyzhykov, I. (Український математичний вісник, 2006)
  • Hardy Type Spaces Estimates for Multilinear Marcinkiewicz Operators 
    Liu, L. (Український математичний вісник, 2005)
    The purpose of this paper is to prove the boundedness for some multilinear operators generated by Marcinkiewicz integral operators and Lipschitz functions on Hardy and Herz-Hardy spaces.
  • Holder Regularity for the Gradients of Solutions of Degenerate Parabolic Systems 
    Lieberman, G.M. (Український математичний вісник, 2006)
    We study a class of parabolic systems of the form vt = div(F(|Dv|Dv). The function F satisfies a few technical hypotheses which are satisfied, for example, by F(s) = sⁿ⁻² with n > 1. Hence our results extend the standard ...
  • Homogenization of Maxwell's Equations in Domains with Dense Perfectly Conducting Grids 
    Khruslov, E.Ya. (Український математичний вісник, 2005)
    We consider Maxwell’s equations in domains that are complements to connected, grid-like sets formed by intersecting thin wires. We impose the boundary conditions that correspond to perfectly conducting wires, and study the ...
  • Hyperbolic metrics on universal Teichmüller space and extremal problems 
    Krushkal, S.L. (Український математичний вісник, 2011)
    The paper consists of two parts, both related to complex geometry of the universal Teichm¨uller space. We reprove that all contractible invariant metrics on this space coincide and apply this important fact to solving the ...
  • Hyperbolic topology and bounded locally homeomorphic quasiregular mappings in 3-space 
    Apanasov, B.N. (Український математичний вісник, 2019)
    We use our new type of bounded locally homeomorphic quasiregular mappings in the unit 3-ball to address long standing problems for such mappings, including the Vuorinen injectivity problem. The construction of such mappings ...
  • H-зрізи напівгрупи часткових ін'єктивних неперервних перетворень гаусдорфового простору 
    Пєхтєрєв, В.О. (Український математичний вісник, 2006)
    У данiй роботi доводиться, що коли напiвгрупа усiх iн’єктивних та неперервних часткових перетворень гаусдорфового простору X у себе вiдносно суперпозицiї мiстить H-зрiз, то простiр X є не бiльш нiж злiченим дискретним ...
  • Improved integrability and boundedness of solutions to some high-order variational problems 
    Voitovych, M.V. (Український математичний вісник, 2018)
    We give a series of results on the improved integrability and boundedness of solutions to several high-order variational problems with strengthened coercivity. In particular, we consider the homogeneous Dirichlet problem ...
  • Initial-boundary value problems for anisotropic elliptic-parabolic-pseudoparabolic equations with variable exponents of nonlinearity 
    Bokalo, M.; Domanska, H. (Український математичний вісник, 2014)
    Existence and uniqueness of weak solutions of initialboundary value problems for anisotropic elliptic-parabolic-pseudoparabolic equations with variable exponents of nonlinearity are proved. Estimates of the weak solutions ...
  • In Memory of Professor Bogdan Bojarski 
    Автор відсутній (Український математичний вісник, 2018)
    Editorial Board of the Ukrainian Mathematical Bulletin was deeply saddened to learn of the passing away on 22 December, 2018 of Bogdan Tadeusz Bojarski, one of the greatest mathematicians of his generation, a brilliant ...
  • In Memory of Professor Sir Michael Francis Atiyah 
    Автор відсутній (Український математичний вісник, 2019)
    The Editorial Board of the international journal “Ukrainian Mathematical Bulletin” has learnt with great sadness of death of Professor Sir Michael Atiyah on January 11th, 2019. Michael Atiyah was a brilliant mathematician ...
