  • Sköldberg, E. (Algebra and Discrete Mathematics, 2018)
    We show that the main result of algebraic Morse theory can be obtained as a consequence of the perturbation lemma of Brown and Gugenheim.
  • Gusev, S.V.; Skokov, D.V.; Vernikov, B.M. (Algebra and Discrete Mathematics, 2018)
    We completely determine all commutative semigroup varieties that are cancellable elements of the lattice SEM of all semigroup varieties. In particular, we verify that a commutative semigroup variety is a cancellable element ...
  • Harmanci, A.; Ungor, B. (Algebra and Discrete Mathematics, 2018)
    This work is devoted to the investigation of module decompositions which arise from Rickart modules, socle and radical of modules. In this regard, the structure and several illustrative examples of inverse split modules ...
  • Kniahina, V.N.; Monakhov, V.S. (Algebra and Discrete Mathematics, 2018)
    A subgroup H of a finite group G is said to be Hall normally embedded in G if there is a normal subgroup N of G such that H is a Hall subgroup of N. A Schmidt group is a non-nilpotent finite group whose all proper subgroups ...
  • Khosravi, R. (Algebra and Discrete Mathematics, 2018)
    This paper shall be concerned with the notion of regular torsionless in the category of S-posets. Besides elementary basic properties of regular torsionless S-posets, we consider cyclic regular torsionless S-posets and ...
  • Kurdachenko, L.A.; Semko, N.N.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2018)
    Lie algebras are exactly the anticommutative Leibniz algebras. In this article, we conduct a brief analysis of the approach to Leibniz algebras which based on the concept of the anti-center (Lie-center) and antinilpotency ...
  • Paudel, L.; Tchamna, S. (Algebra and Discrete Mathematics, 2018)
    Let R ⊆ S be a ring extension, and let A be an R-submodule of S. The saturation of A (in S) by τ is set A[τ] = {x ∈ S : tx ∈ A for some t ∈ τ}, where τ is a multiplicative subset of R. We study properties of saturations ...
  • Gómez González, F.A.; Velasquez, R. (Algebra and Discrete Mathematics, 2018)
    An analogue of the Wedderburn Principal Theorem (WPT) is considered for finite-dimensional Jordan superal-gebras A with solvable radical N, N² = 0, and such that A/N ≅ Jospn|2m(F), where F is a field of characteristic zero. ...
  • Vadhel, P.; Visweswaran, S. (Algebra and Discrete Mathematics, 2018)
    The rings considered in this article are nonzero commutative with identity which are not fields. Let R be a ring. We denote the collection of all proper ideals of R by I(R) and the collection I(R)\{(0)} by I(R)*. Recall ...
  • Young Bae Jun; Kyoung Ja Lee; Seok Zun Song (Algebra and Discrete Mathematics, 2018)
    The notion of PI-quasi-valuation maps of a BCK-algebra is introduced, and related properties are investigated. The relationship between an I-quasi-valuation map and a PI-quasivaluation map is examined. Conditions for an ...
  • Zabavsky, B.V. (Algebra and Discrete Mathematics, 2018)
    This article deals mostly with the following question: when the classical ring of quotients of a commutative ring is a ring of stable range 1? We introduce the concepts of a ring of (von Neumann) regular range 1, a ring ...
  • Ahmia, M.; Belbachir, H. (Algebra and Discrete Mathematics, 2018)
    This paper is an extension of Boros and Moll’s result “A criterion for unimodality”, who proved that the polynomial P(x + 1) is unimodal.
  • Desiateryk, O.O.; Ganyushkin, O.G. (Algebra and Discrete Mathematics, 2018)
    In this paper we consider the ordered by inclusion lattice Part(M) of all partitions of a countable set M. The lattice Part(M) is a semigroup with respect to the operation Λ which maps two partitions to their greatest ...
