  • Ponizovskii, J.S. (Algebra and Discrete Mathematics, 2004)
    A concept of basic matrix semigroups over fields (with some variations) is introduced and throughly investigated. Sections 1 and 2 contain main definitions, Section 3 treats some properties of basic semigroups, Section ...
  • Denecke, K.; Jampachon, P. (Algebra and Discrete Mathematics, 2004)
    In this paper the well-known connection between hyperidentities of an algebra and identities satisfied by the clone of this algebra is studied in a restricted setting, that of n-ary full hyperidentities and identities ...
  • Wisbauer, R. (Algebra and Discrete Mathematics, 2004)
    For a ring R, call a class C of R-modules (pure-) mono-correct if for any M, N ∈ C the existence of (pure) monomorphisms M → N and N → M implies M ≃ N. Extending results and ideas of Rososhek from rings to modules, it ...
  • Shemetkova, O. (Algebra and Discrete Mathematics, 2004)
    Let H be a normal subgroup of a finite group G. A number of authors have investigated the structure of G under the assumption that all minimal or maximal subgroups in Sylow subgroups of H are well-situated in G. A general ...
  • Kulikova, O.V. (Algebra and Discrete Mathematics, 2004)
    The paper is a generalization of [2]. For a group H = ‹A|O›, conditions for the equality Ñ₁ ∩ Ñ₂ = Ñ₁, Ñ₂] are given in terms of pictures, where Ñi is the normal closure of a set R¯ i ⊂ H for i = 1, 2.
  • Sonkin, D. (Algebra and Discrete Mathematics, 2004)
    It is shown that the set of pairwise non-isomorphic 2-generated simple groups of exponent n (n ≥ 2⁴⁸ and n is odd or divisible by 2⁹ ) is of cardinality continuum. As a corollary, for any sufficiently large n the ...
  • Grillet, P.A. (Algebra and Discrete Mathematics, 2004)
    Partial resolutions are constructed for the EilenbergMacLane cohomology of monoids, with applications to examples.
  • Novikov, B.V.; Polyakova, L.Yu. (Algebra and Discrete Mathematics, 2004)
