  • Zotov, A.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We study 1+1 field-generalizations of the rational and elliptic Gaudin models. For sl(N) case we introduce equations of motion and L-A pair with spectral parameter on the Riemann sphere and elliptic curve. In sl(2) case ...
  • Ananieva, A.Yu. (Український математичний вісник, 2016)
    We study spectral properties of the One-dimensional Schrodinger operators.
  • Dario, R.P.; Engler, A.J. (Algebra and Discrete Mathematics, 2010)
    An accurate description of the Galois group GF(2) of the maximal Galois 2-extension of a field F may be given for fields F admitting a 2-henselian valuation ring. In this note we generalize this result by characterizing ...
  • Домша, О.В. (Український математичний журнал, 2010)
    Известно, что простая область Безу является областью элементарных делителей тогда и только тогда, когда она 2-простая. В работе доказано, что над 2-простой областью Орэ стабильного ранга 1 произвольная матрица, не являющаяся ...
  • Иванова, А.А. (Труды Института прикладной математики и механики, 2011)
    Представлена трехмерная математическая модель нестационарного температурного поля непрерывнолитой заготовки и стенок кристаллизатора. Модель учитывает зависимости теплофизических параметров от температуры, наличие зазора ...
  • Kirichenko, V.V.; Sushchansky, V.I.; Varbanets, P.D. (Algebra and Discrete Mathematics, 2006)
    This volume contains papers based on the talks presented at the 5t h In- ternational Algebraic Conference in Ukraine, which took place in Ode ssa on July 20–27, 2005. The conference was organized by Odessa I. I. ...
  • An, H.; Rogers, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    A 2+1-dimensional anisentropic magnetogasdynamic system with a polytropic gas law is shown to admit an integrable elliptic vortex reduction when γ=2 to a nonlinear dynamical subsystem with underlying integrable Hamiltonian-Ermakov ...
  • Ol’shanskii, A.Yu.; Sapir, M.V. (Algebra and Discrete Mathematics, 2007)
    We construct a 2-generated 2-related group without non-trivial finite factors-groups. This answers a question of J. Button.
  • Chilin, V.; Litvinov, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    Utilizing the notion of uniform equicontinuity for sequences of functions with the values in the space of measurable operators, we present a non-commutative version of the Banach Principle for L∞.
  • Tomkinson, M.J. (Український математичний журнал, 1991)
    A splitting Theorem for FC-hypercentral group G and ZG-module of finite rank is obtained. According to this Theorem, under certain conditions, every extention E of the ZG-module A by the group G is split and all the ...
  • Kurdachenko, L.A.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2005)
    t. Some properties of abnormal subgroups in generalized soluble groups are considered. In particular, the transitivity of abnormality in metahypercentral groups is proven. Also it is proven that a subgroup H of a radical ...
  • Vinet, L.; Zhedanov, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We establish an analogue of the Bochner theorem for first order operators of Dunkl type, that is we classify all such operators having polynomial solutions. Under natural conditions it is seen that the only families of ...
  • Gorodetsky, V.V.; Drin, I.I. (Нелинейные граничные задачи, 1999)
  • Marinets, V.V.; Dobryden, A.V. (Нелінійні коливання, 2001)
    The characteristic initial value problem has been studied for the second order nonlinear differential equation, and modifications of the two-sided method of its approximate integration have been constructed.
  • 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.
  • 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.
  • Salimov, R.R.; Sevost'yanov, E.A. (Труды Института прикладной математики и механики, 2012)
    The present paper is devoted to the study of space mappings which are more general than quasiregular. The so-called modulus inequalities of the order p, p ≥ 1, and it’s connections with space mappings are investigated. The ...
  • Omel'chenko, P.V. (2009)
    In the present paper we study *-representations of semilinear relations with polynomial characteristic functions. For any finite simple non-oriented graph Г we construct a polynomial characteristic function such that Г is ...
  • Salimov, R.; Afanas'eva, O. (Труды Института прикладной математики и механики, 2013)
    It is formulated conditions on functions Q(x) and boundaries of domains under which every Q-homeomorphism admits continuous or homeomorphic extension to the boundary in metric spaces with measures.
  • Elhadj, Z.; Sprott, J.C. (Нелінійні коливання, 2010)
    Наведено узагальнення всiх вiдомих результатiв про верхню границю для загальної 3-D квадратичної системи з неперервним часом. Зокрема, знайдено великi областi у просторi бiфуркацiйного параметра системи, де система є обмеженою.
