  • Sastry, B.R.; Murty, K.N.; Balaram, V.V.S.S.S. (Электронное моделирование, 2007)
    This paper is concerned with the existence and uniqueness of solutions to two-point boundary value problems associated with general first order matrix difference systems. Modified Gram—Schmidt process and modified QR-algorithm ...
  • Rezaei Sh. (Algebra and Discrete Mathematics, 2020)
    Let (R,m) be a local ring, Ф a system of ideals of R and M a finitely generated R-module. In this paper, we define and study general formal local cohomology modules. We denote the i-th general formal local cohomology module ...
  • Henrique N. Sá Earp (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    Adjusting conventional Chern-Simons theory to G₂-manifolds, one describes G₂-instantons on bundles over a certain class of 7-dimensional flat tori which fiber non-trivially over T⁴, by a pullback argument. Moreover, if ...
  • Howie, J. (Algebra and Discrete Mathematics, 2013)
    If G is a group with a presentation of the form ⟨x, y|x³ = yq = W(x, y)² = 1⟩, then either G is virtually soluble or G contains a free subgroup of rank 2. This provides additional evidence in favour of a conjecture of Rosenberger.
  • Jaber, A. (Algebra and Discrete Mathematics, 2016)
    Let R be a commutative super-ring with unity 16= 0. A proper super ideal of R is a super ideaI of R such that I 6=R.Letφ:I(R)→I(R)∪ {∅}be any function, where I(R) denotes the set of all proper super ideals of R. A homogeneous ...
  • Gorev, V.N.; Sokolovsky, A.I. (Condensed Matter Physics, 2017)
    The Grad method is generalized based on the Bogolyubov idea of the functional hypothesis for states at the end of relaxation processes in a system. The Grad problem (i.e., description of the Maxwell relaxation) for a ...
  • Aminov, Yu.; Witkowska, J. (2007)
    We proved two theorems on stability of minimal submanifolds in a Riemannian space, which can be included in a regular family of minimal submanifolds.
  • Bratyk, M.; Mishura, Y. (2008)
    The paper is devoted to the problem of quantile hedging of contingent claims in the framework of a model defined by the finite number of independent Brownian and fractional Brownian motions. The maximal success probability ...
  • Serdiuk, O.; Petrova, I. (Економічний вісник Донбасу, 2020)
    A comparative analysis of the tools of internalization of negative external. Based on the generalization and assessment of the possibilities of using the tools of internalization of negative externalities, the areas of ...
  • Golasinski, M.; Goncalves, D.; Wong, P. (Український математичний журнал, 2005)
    In this paper, we redefine the torus homotopy groups of Fox and give a proof of the split exact sequence of these groups. Evaluation subgroups are defined and are related to the classical Gottlieb subgroups. With our ...
  • Darani, A.Y.; Mostafanasab, H. (Algebra and Discrete Mathematics, 2016)
    This article introduces the notions quasi-co-n-absorbing preradicals and semi-co-n-absorbing preradicals, generalizing the concept of semicoprime preradicals. We study the concepts quasi-co-n-absorbing submodules and ...
  • Pečarić, J.; Perušić, A.; Smoljak, K. (Український математичний журнал, 2015)
    We obtain generalizations of Steffensen’s inequality by using Lidstone’s polynomials. Furthermore, the functionals associated with the obtained generalizations are used to generate n-exponentially and exponentially convex ...
  • Türkmen, B.N.; Pancar, A. (Український математичний журнал, 2013)
    We introduce ⊕-radical supplemented modules and strongly ⊕-radical supplemented modules (briefly, srs⊕-modules) as proper generalizations of ⊕-supplemented modules. We prove that (1) a semilocal ring R is left perfect if ...
  • ‎Ansari-Toroghy, H.; Farshadifar, F.; ‎Maleki-Roudposhti, S. (Algebra and Discrete Mathematics, 2020)
    In this paper, we will introduce the concepts of generalized 2-absorbing and strongly generalized 2-absorbing second submodules of modules over a commutative ring and obtain some related results.
  • He, J.H. (Механика твердого тела, 2001)
    In this paper, we begin with the Lagrangian L = T - V , the difference between the kinetic and potential energies, by introducing some constraints, and applying the Lagrange multiplier, we obtain various forms of generalized ...
  • Demni, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    We write down the generalized Bessel function associated with the root system of type D by means of multivariate hypergeometric series. Our hint comes from the particular case of the Brownian motion in the Weyl chamber of type D.
  • Sekatski, S.K. (Український математичний журнал, 2014)
    We show that Li’s criterion equivalent to the Riemann hypothesis, i.e., the statement that the sums kn=Σρ(1−(1−1ρ)n) over zeros of the Riemann xi-function and the derivatives are nonnegative if and only if the Riemann ...
  • Jaipong, P.; Tapanyo, W. (Algebra and Discrete Mathematics, 2019)
    Let Г be the modular group. We extend a nontrivial Г-invariant equivalence relation on Q to a general relation by replacing the group Г₀(n) by Гк(n), and determine the suborbital graph Fᴷu,n, an extended concept of the ...
  • Cheng, T.; Huang, H.-L.; Yang, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    By viewing Clifford algebras as algebras in some suitable symmetric Gr-categories, Albuquerque and Majid were able to give a new derivation of some well known results about Clifford algebras and to generalize them. Along ...
  • Hassanzadeh, M.; Kucerovsky, D.; Rangipour, B. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    A category of coefficients for Hopf cyclic cohomology is defined. It is shown that this category has two proper subcategories of which the smallest one is the known category of stable anti Yetter-Drinfeld modules. The ...
