  • 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

    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

  • 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 ...
  • On a classical solvability of a Florin problem 
    Bizhanova, G.I. (Український математичний вісник, 2008)
    There is considered the multidimensional two-phase Stefan problem with a small parameter k at the velocity of a free boundary in a Stefan condition. The unique solvability and coercive uniform with respect to k estimate ...
  • On a model semilinear elliptic equation in the plane 
    Gutlyanskii, V.Y.; Nesmelova, O.V.; Ryazanov, V.I. (Український математичний вісник, 2016)
    Assume that Ω is a regular domain in the complex plane C and A(z) is symmetric 2 × 2 matrix with measurable entries, det A = 1 and such that 1/K|ξ|² ≤ 〈A(z)ξ, ξ〉 ≤ K|ξ|², ξ ∊ R², 1 ≤ K < ∞. We study the blow-up problem ...

    Andrievskii, V.V. (Український математичний вісник, 2004)
    This is a survey of some recent results by the author and his collaborators in the constructive theory of functions of a real variable. The results are achieved by the application of methods and techniques of modern geometric ...
  • On convergence theory for Beltrami equations

    Ryparova, L.; Mikes, J.; Sabykanov, A. (Український математичний вісник, 2018)
    The bifurcation is described as a situation where there exist at least two different geodesics going through the given point in the given direction. In the previous works, the examples of local and closed bifurcations are ...
  • On integral conditions in the mapping theory 
    Ryazanov, V.; Srebro, U.; Yakubov, E. (Український математичний вісник, 2010)
    It is established interconnections between various integral conditions that play an important role in the theory of space mappings and in the theory of degenerate Beltrami equations in the plane.
  • On kinetic formulation of first-order hyperbolic quasilinear systems 
    Panov, E.Yu. (Український математичний вісник, 2004)
