  • The Linearity Problem for the Unitriangular Automorphism Groups of Free Groups 

    Roman’kov, Vitaly A.; Романьков, Виталий А. (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    We prove that the unitriangular automorphism group of a free group of rank n has a faithful representation by matrices over a field, or in other words, it is a linear group, if and only if n 3. Thus, we have completed ...
  • Optimization Problems with Random Data 

    Popova, Olga A.; Попова, Ольга А. (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    The article discusses a new approach to optimization problems with random input parameters, which is defined as a random programming. This approach uses a numerical probability analysis and allows us to construct the set ...
  • Applications of Operational Approach to Evaluation of Projects of Economic Systems Development 

    Pobedash, Pavel N.; Победаш, Павел Н. (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    The paper proposes a technique of obtaining the investment project optimal cost for the development of economic systems. The considered systems are described by multi-step multicriteria linear programming problems with ...
  • On Solvability of an Inverse Boundary Value Problem for the Boussinesq–Love Equation 

    Mehraliyev, Yashar T.; Мегралиев, Яшар Т. (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    In the paper an inverse boundary value problem for the Boussinesq-Love equation with an integral con- dition of the first kind is investigated. First, the given problem is reduced to an equivalent problem in a certain ...

    Model problems for two nonlinear second-order partial differential equations that type depends on the solution are considered in this article. One of the equations can be called a nonlinear analog of the Lavrent’ev-Bitsadze ...
  • Sharp Theorems on Traces in Analytic Spaces in Tube Domains over Symmetric Cones

    New sharp estimates of Traces in Bergman-type spaces of analytic functions on tube domains over symmetric cones are obtained.These are first results of this type for tube domains over symmetric cones
  • Equationally Noetherian Algebras and Chain Conditions 

    Shahryari, Mohammad; Шахриари, Мохамад (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    In this article, we describe the relation between the properties of being equational noetherian and ascending chain condition on ideals of an arbitrary algebra. We also give a formulation of Hilbert’s basis theorem for ...
  • Approximate Integration of Modified Riesz Potentials 

    Medvedeva, Maria I; Osipov, Nikolay N.; Медведева, Мария И.; Осипов, Николай Н. (Сибирский федеральный университет. Siberian Federal University., 2013-11)
    The estimates for the errors of quadrature formulas are deduced in the case of integration of potentials such as the Feller potential, which is a modification of the Riesz potential
