  • Dario, R.P.; Engler, A.J. (Algebra and Discrete Mathematics, 2010)
    An accurate description of the Galois group GF(2) of the maximal Galois 2-extension of a field F may be given for fields F admitting a 2-henselian valuation ring. In this note we generalize this result by characterizing ...
  • Dabbaghian, V. (Algebra and Discrete Mathematics, 2010)
    Let G be a non-abelian non-simple group. In this article the group G such that G=MCG(M) will be studied, where M is a proper maximal subgroup of G and CG(M) is the centralizer of M in G.
  • Oliynyk, A. (Algebra and Discrete Mathematics, 2010)
    It is established a criterion when the infinite wreath power of a finite transformation semigroup contains a free subsemigroup. It is shown that the infinite wreath power of a transformation semigroup either contains no ...
  • Calısıcı, H.; Turkmen, E. (Algebra and Discrete Mathematics, 2010)
    Let R be a ring and M be a left R-module. M is called generalized ⊕- supplemented if every submodule of M has a generalized supplement that is a direct summand of M. In this paper we give various properties of such modules. ...
  • Buyukasık, E. (Algebra and Discrete Mathematics, 2010)
    Let R be a ring and τ be a preradical for the category of left R-modules. In this paper, we study on modules whose maximal submodules have τ-supplements. We give some characterizations of these modules in terms their ...
  • Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2010)
    The author studies an RG-module A such that R is a commutative ring, A/CA(G) is not a Noetherian R-module, CG(A)=1, G is a soluble group. The system of all subgroups H≤G, for which the quotient modules A/CA(H) are not ...
  • Ikehata, S. (Algebra and Discrete Mathematics, 2010)
    Let B be a ring with 1, and {ρ1,⋯,ρe} a set of automorphisms of B. Let B[X1,⋯,Xe;ρ1,⋯,ρe;{uij}] be the skew polynomial ring of automorphism type. In this paper, we shall give equivalent conditions that the residue ring of ...
  • Zhiznevsky, P. (Algebra and Discrete Mathematics, 2010)
    In the universe of finite groups the description of τ-closed n-multiply ω-composition formations with Boolean sublattices of τ-closed n-multiply ω-composition subformations is obtained.
  • Zemlicka, J. (Algebra and Discrete Mathematics, 2010)
    A module M is said to be small if the functor Hom(M,−) commutes with direct sums and right steady rings are exactly those rings whose small modules are necessary finitely generated. We give several results on steadiness ...
  • Dupont, L.D.; Villarreal, R.H. (Algebra and Discrete Mathematics, 2010)
    Let G be a simple graph and let Ic(G) be its ideal of vertex covers. We give a graph theoretical description of the irreducible b-vertex covers of G, i.e., we describe the minimal generators of the symbolic Rees algebra ...
