  • The Solution of Algebraic Equations of Continuous Fractions of Nikiports 

    Shmoylov, Vladimir I.; Kirichenko, Gennadiy A.; Шмойлов, Владимир И.; Кириченко, Геннадий А. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    Analytical expressions representing all the roots of a random algebraic equation of n-th degree in terms of the equation coefficients are presented in the paper. These formulas consist of two ratios of infi- nite Toeplitz ...

  • Very Low Ergodicity of Real Genomes 

    Sadovsky, Michael G.; Nikitina, Ksenia A.; Садовский, Михаил Г.; Никитина, Ксения А. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    A distribution of the longest distances to the nearest neighbour alongside a genetic sequence is investi- gated. It is shown the real DNA sequences differ basically from any model one, while the figures of the distribution ...

  • Some Examples of Finding the Sums of Multiple Series 

    Myshkina, Evgeniya K.; Мышкина, Евгения К. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    A method of finding residue integrals for some systems of non-algebraic equations are presented. Such integrals are connected to the power sums of roots for the system of equations. It is shown how the obtained results ...

  • The Study of Discrete Probabilistic Distributions of Random Sets of Events Using Associative Function 

    Lukyanova, Natalia A.; Semenova, Daria V.; Лукьянова, Наталья А.; Семенова, Дарья В. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    In this work the class of discrete probabilistic distributions of the II-nd type of random sets of event is investigated. As the tool for constructing of such probabilistic distributions it is offered to use associative ...

  • On the Zeta-Function of Zeros of Some Class of Entire Functions 

    Kuzovatov, Vyacheslav I.; Kytmanov, Alexey A.; Кузоватов, Вячеслав И.; Кытманов, Алексей А. (2014-11)
    Using the residue theory, we give an integral representation for the zeta-function that enables us to construct its analytic continuation

  • Solving Yang-Mills Equations for 4-metrics of Petrov Types II, N, III 

    Krivonosov, Leonid N.; Lukyanov, Vyacheslav A.; Кривоносов, Леонид Н.; Лукьянов, Вячеслав А. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    We have produced 4 series of 4-metrics satisfying Yang-Mills equations for each of types II, N, III

  • Boundary Version of the Morera Theorem for a Matrix Ball of the Second Type 

    Khudayberganov, Gulmirza Kh.; Matyakubov, Zokirbek K.; Худайберганов, Гулмирза Х.; Матайкубов, Зокирбек М. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    In this article we prove a boundary Morera theorem for a matrix ball of the second type

  • On Some Systems of Non-algebraic Equations in Cn 

    Khodos, Olga V.; Ходос, Ольга В. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    A method of finding residue integrals for systems of non-algebraic equations containing entire functions is presented in the paper. Such integrals are connected with the power sums of roots of certain system of equations. ...

  • On Long-Term Behavior of Continuous-Time Markov Branching Processes Allowing Immigration 

    Imomov, Azam A.; Имомов, Азам А. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    We observe the continuous-time Markov Branching Process allowing Immigration. Limit properties of transition functions and their convergence to invariant measures are investigated. A speed of this con- vergence is defined

  • Energy Method for Mathematical Modeling of Heat Transfer in 2-D Flow 

    Denisenko, Valery V.; Денисенко, Валерий В. (Сибирский федеральный университет. Siberian Federal University., 2014-11)
    A multigrid finite element method for 2-D convection-heat transfer problem is proposed. The method is based on minimization of the energy functional. Effectiveness of the method is demonstrated by calculation of temperature ...
