  • On solvable Z₃-graded alternative algebras 
    Goncharov, M. (Algebra and Discrete Mathematics, 2015)
    Let A=A₀⊕A₁⊕A₂ be an alternative Z₃-graded algebra. The main result of the paper is the following: if A0 is solvable and the characteristic of the ground field not equal 2,3 and 5, then A is solvable.
  • On strongly almost m-ω₁-pʷ⁺ⁿ-projective abelian p-groups 
    Danchev, P. (Algebra and Discrete Mathematics, 2015)
    For any non-negative integers man dn we define the class of strongly almost m-ω₁-pʷ⁺ⁿ-projective groups which properly encompasses the classes of strongly m-ω₁-pω⁺ⁿ-projective groups and strongly almost ω₁-pʷ⁺ⁿ-projective ...
  • On the le-semigroups whose semigroup of bi-ideal elements is a normal band 
    Bhuniya, A.K.; Kumbhakar, M. (Algebra and Discrete Mathematics, 2015)
    It is well known that the semigroup B(S) of all bi-ideal elements of an le-semigroup S is a band if and only if S is both regular and intra-regular. Here we show that B(S) is a band if and only if it is a normal band and ...
  • Quasi-Euclidean duo rings with elementary reduction of matrices 
    Romaniv, O.; Sagan, A. (Algebra and Discrete Mathematics, 2015)
    We establish necessary and sufficient conditions under which a class of quasi-Euclidean duo rings coincides with a class of rings with elementary reduction of matrices. We prove that a Bezout duo ring with stable range 1 ...
  • The lower bound for the volume of a three-dimensional convex polytope 
    Kawaguchi, R. (Algebra and Discrete Mathematics, 2015)
    In this paper, we provide a lower bound for the volume of a three-dimensional smooth integral convex polytope having interior lattice points. Our formula has a quite simple form compared with preliminary results. Therefore, ...
  • Vector bundles on projective varieties and representations of quivers 
    Jardim, M.; Prata, D.M. (Algebra and Discrete Mathematics, 2015)
    We present equivalences between certain categories of vector bundles on projective varieties, namely cokernel bundles, Steiner bundles, syzygy bundles, and monads, and full subcategories of representations of certain ...
