  • 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 ...

    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 ...
  • Kaleidoscopical configurations 
    Protasov, І.; Protasova, K. (Український математичний вісник, 2014)
    Let G be a group and X be a G-space with the action G × X → X, (g, x) → gx. A subset A of X is called a kaleidoscopical configuration if there is a coloring χ : X → k (i.e. a mapping of X onto a cardinal k) such that the ...
  • Keller-Osserman a priori estimates and removability result for the anisotropic porous medium equation with absorption term 
    Shan, M.A. (Український математичний вісник, 2018)
    We obtain the removability result for quasilinear equations of the special form and prove a priori estimates of the Keller–Osserman type.
  • K-дифференцируемость и K-экстремумы 
    Орлов, И.В. (Український математичний вісник, 2006)
    Исследуются свойства компактных экстремумов функционалов в локально выпуклом пространстве, в частности, интегральных функционалов. Рассмотрены примеры.
  • Large deviations for random evolutions with independent increments in a scheme of Levy approximation 
    Samoilenko, I.V. (Український математичний вісник, 2015)
    Asymptotic analysis of the problem of large deviations for random evolutions with independent increments in the circuit of the L´evy approximation is carried out. Large deviations for random evolutions in the circuit of ...
  • Lateral ideals of ternary semigroups 
    Iampan, A. (Український математичний вісник, 2007)
    In this paper, we give some auxiliary results are also necessary for our considerations and characterize the relationship between the (0-)minimal and maximal lateral ideals and the lateral simple and lateral 0-simple ternary ...
  • Levy approximation of processes with locally independent increments with semi-Markov switching 
    Koroliuk, V.S.; Limnios, N.; Samoilenko, I.V. (Український математичний вісник, 2009)
  • Local sub-estimates of solutions to double phase parabolic equations via nonlinear parabolic potentials 
    Buryachenko, K.O. (Український математичний вісник, 2019)
    For parabolic equations with nonstandard growth conditions, we prove local boundedness of weak solutions in terms of nonlinear parabolic potentials of the right-hand side of the equation.
  • Monogenic functions in commutative algebras associated with classical equations of mathematical physics 
    Plaksa, S.A. (Український математичний вісник, 2018)
    The methods involving the functions analytic in a complex plane for plane potential fields inspire the search for the analogous efficient methods for solving the spatial and multidimensional problems of mathematical physics. ...
  • More Examples of Hereditarily ℓp Banach Spaces 
    Popov, M.M. (Український математичний вісник, 2005)
    Extending our previous result, we construct a class of hereditarily ℓp for 1 ≤ p < ∞ (c₀) Banach spaces, investigate their properties, and show that the classical Pitt theorem on compactness of operators from ℓs to ℓp for ...
  • n-distributivity and n-modularity in lattices 
    Skowronek-Kaziow, J. (Український математичний вісник, 2004)
    In this paper we consider some forbidden sublattices for n-distributive, but non-modular lattices. We define the new notion of n-modularity (weaker than n-distributivity). We also consider some forbidden sublattice for an ...
  • Neumann problem in a disk for fourth-order improperly elliptic equations 
    Buryachenko, K.O.; Kudrych, Y. (Український математичний вісник, 2017)
    We have established and investigated the sufficient conditions of solvability of the Neumann problem for all classes of fourth-order improperly elliptic equatios in a unit disk K in the space C⁴(K) ∩ C³,ª(K).
  • Nonlinear calculus of variations for differential flows on manifolds: geometrically correct introduction of covariant and stochastic variations 
    Antoniouk, A.Val; Antoniouk, A.Vict. (Український математичний вісник, 2004)
    We consider flows, generated by nonlinear differential equations on manifold that could also contain random terms and correspond to the second order parabolic equations. We demonstrate that the rigorous statement of the ...
  • On 2-primal Ore extensions 
    Bhat, V.K. (Український математичний вісник, 2007)
    Let R be a ring, be an automorphism of R and δ be a σ-derivation of R. We define a δ property on R. We say that R is a δ-ring if aδ(a) ∊ P(R) implies a ∊ P(R), where P(R) denotes the prime radical of R. We ultimately ...
