  • On size effect of mechanical properties of thermoelastic solids 
    Nahirnyj, T.; Tchervinka, K. (Фізико-математичне моделювання та інформаційні технології, 2009)
    In this paper the principal relations of a thermoelastic solid model for the local gradient approach in thermomechanics are presented. Within the framework of such an approach the stationary stressed-strained state of a ...
  • On small world non-Sunada twins and cellular Voronoi diagrams 
    Ustimenko, V. (Algebra and Discrete Mathematics, 2020)
    Special infinite families of regular graphs of unbounded degree and of bounded diameter (small world graphs) are considered. Two families of small world graphs Gi and Hi form a family of non-Sunada twins if Gi and Hi are ...

    Zolotenko, G.F. (Нелінійні коливання, 2001)
    The problem of integrating the Laplace equation in a changing 3-dimensional region, with the initial and boundary conditions, is investigated. The paper is mainly devoted to the problem arising in dynamics of an inviscid ...
  • On solvability for evolutionary variational inequality with set-valued generalized pseudomonotone operators 
    Solonukha, O. (Нелинейные граничные задачи, 2003)
    The sufficient conditions for weak and strong generalized solvability of evolutionary variational inequalities with set-valued operators are proposed. We consider the operators of pseudomonotone type. We apply this theory ...
  • On solvability of inhomogeneous boundary-value problems in Sobolev—Slobodetskiy spaces 
    Mikhailets, V.A.; Skorobohach, T.V. (Доповіді НАН України, 2020)
    We investigate the most general class of Fredholm one-dimensional boundary-value problems in the Sobolev—Slobodetskiy spaces. Boundary conditions of these problems may contain a derivative of the whole or fractional order. ...
  • On solvability of singular periodic boundary-value problems 
    Staněk, S. (Нелінійні коливання, 2001)
    We present conditions ensuring the existence of a solution in the class C¹ ([0, T]) for the singular periodic boundary-value problem (r(x' ))' = H(p(t) + q(x))k(x')f(t, x, x'(0) = x(T), x'(0) = x'(T).
  • On solvability of the variational inequality with +-coercive multivalued mappings 
    Solonoukha, O.V. (Нелинейные граничные задачи, 1999)
    In this work the theory of variational inequalities with multivalued operators is extended for the wider of multivalued maps from the re°exive Banach space to its dual one. In particular, we relax the restriction on boundness ...
  • On solvable Z₃-graded alternative algebras 
    Goncharov, M. (Algebra and Discrete Mathematics, 2015)
    Let A=A₀⊕A₁⊕A₂ be an alternative Z₃-graded algebra. The main result of the paper is the following: if A0 is solvable and the characteristic of the ground field not equal 2,3 and 5, then A is solvable.
  • On some aspects of the theory of modules over group rings 
    Kirichenko, V.V.; Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2009)
    The authors discuss some recent developments in the theory of modules over group rings.
  • On some characteristics of the claim surplus process 
    Gusak, D. (2008)
    The distribution of characteristics, which describes the behaviour of the claim surplus process after the ruin, is investigated and compared with some previous results on distributions of risk functionals. Main attention ...
  • On some commutative invariants of modules over minimax nilpotent groups 
    Tushev, A.V. (Доповіді НАН України, 2022)
    In the paper we introduce a finite system of invariants for modules over minimax nilpotent groups which consists of classes of equivalent prime ideals of the group algebra of an Abelian minimax group. In particuly, ...
  • On some developments in investigation of groups with prescribed properties of generalized normal subgroups 
    Kirichenko, V.V.; Kurdachenko, L.A. (Algebra and Discrete Mathematics, 2010)
    The survey is dedicated to investigation of groups with prescribed properties of generalized normal subgroups. The roots of such investigations lie in the works by R. Dedekind, R. Baer, O.Yu.Schmidt, and S.N. Chernikov. ...

    Sushch, V. (Нелинейные граничные задачи, 2003)
    Using methods of differential geometry, a discrete analog of the Yang-Mills equations in Minkowski space is constructed. The gauge transformation law in a discrete formulation is given and gauge invariance of discrete ...
