  • 1+1 Gaudin Model 
    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 ...
  • 1-D Schrodinger operators with local interactions on a discrete set with unbounded potentia 
    Ananieva, A.Yu. (Український математичний вісник, 2016)
    We study spectral properties of the One-dimensional Schrodinger operators.
  • 2-Galois groups and the Kaplansky radical 
    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 ...
  • 2-прості області Оре стабільного рангу 1 
    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 ...
  • 3-D математическая модель температурного поля непрерывного слитка 
    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 ...
  • 5th International Algebraic Conference in Ukraine 
    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. ...
  • A 2+1-Dimensional Non-Isothermal Magnetogasdynamic System. Hamiltonian-Ermakov Integrable Reduction 
    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 ...
  • A 2-generated 2-related group with no non-trivial finite quotients 
    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.
  • A Banach Principle for Semifinite von Neumann Algebras 
    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∞.
  • Abelian-by-FC-hypercentral groups 
    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 ...
  • Abelian doppelsemigroups 
    Zhuchok, A.V.; Knauer, K. (Algebra and Discrete Mathematics, 2018)
    A doppelsemigroup is an algebraic system consisting of a set with two binary associative operations satisfying certain identities. Doppelsemigroups are a generalization of semigroups and they have relationships with such ...
  • Abnormal subgroups and Carter subgroups in some infinite groups 
    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 ...
  • A Bochner Theorem for Dunkl Polynomials 
    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 ...
  • About bounded properties of smooth solutions of some differential-operator equations 
    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.
  • About one extremal problem for projections of the points on unit circle 
    Targonskii, A.L. (Український математичний вісник, 2018)
