  • Dreyfus, T.; Roques, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    This paper is concerned with difference equations on elliptic curves. We establish some general properties of the difference Galois groups of equations of order two, and give applications to the calculation of some difference ...
  • Futorny, V.; Schwarz, J. (Algebra and Discrete Mathematics, 2017)
    In this survey we discuss the theory of Galois rings and orders developed in ([20], [22]) by Sergey Ovsienko and the first author. This concept allows to unify the representation theories of Generalized Weyl Algebras ([4]) ...
  • Blaschke, D.N.; Kronberger, E.; René I.P. Sedmik; Wohlgenannt, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)
    The aim of this review is to present an overview over available models and approaches to non-commutative gauge theory. Our main focus thereby is on gauge models formulated on flat Groenewold-Moyal spaces and renormalizability, ...
  • Dimitrijević, M.; Jonke, L.; Pachoł, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    We review the application of twist deformation formalism and the construction of noncommutative gauge theory on κ-Minkowski space-time. We compare two different types of twists: the Abelian and the Jordanian one. In each ...
  • Chapovsky, Yu. (Український математичний журнал, 1994)
    A pair of a compact quantum group and a coideal in its dual Hopf *-algebra is considered. A notion of a Gelfand pair and a strict Gelfand pair is introduced. For a strict Gelfand pair, two hypercomplex systems dual to each ...
  • Gilewicz, J.; Pindor, M. (Український математичний журнал, 2010)
    We present a review of all interesting results concerning the c-table obtained by the authors for the last two decades. These results are not widely known because they were presented in publications of limited circulation. ...
  • Bojarski, B.V.; Gutlyanskii, V.V.; Ryazanov, V.I. (Український математичний вісник, 2008)
    We study the Beltrami equations ∂f = μ(z)∂f + ν(z)∂f under the assumption that the coefficients μ, ν satisfy the inequality |μ| + |ν| < 1 almost everywhere. Sufficient conditions for the existence of homeomorphic ACL ...
  • Díaz-Marín, H.G. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    We propose a general reduction procedure for classical field theories provided with abelian gauge symmetries in a Lagrangian setting. These ideas come from an axiomatic presentation of the general boundary formulation (GBF) ...
  • 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 ...
  • 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 ...
  • 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.
