    Let G be a group, let S be a subgroup with infinite index in G and let FSG be a certain Z2G-module. In this paper, using the cohomological invariant E(G,S,FSG) or simply E~(G,S) (defined in [2]), we analyze some results ...

    Let n≥2 be a positive integer, K an arbitrary field, and q=[q⁽¹⁾|…|q⁽ⁿ⁾] an n-block matrix of n×n square matrices q⁽¹⁾,…,q⁽ⁿ⁾ with coefficients in K satisfying the conditions (C1) and (C2) listed in the introduction. We ...
  • Cangelmi, L.; Muktibodh, A.S. (Algebra and Discrete Mathematics, 2010)
    Let G be a finite group having a proper normal subgroup K such that the conjugacy classes outside K coincide with the cosets of K. The subgroup K turns out to be the derived subgroup of G, so the group G is either abelian ...
  • Barreiro, E. (Algebra and Discrete Mathematics, 2010)
    We present some properties of odd-quadratic Malcev superalgebras. The aim of this paper is to present the notions of double extension and generalized double extension of odd-quadratic Malcev superalgebras, culminating in ...
  • Favorov, S.; Kolbasina, Y. (Algebra and Discrete Mathematics, 2010)
    A discrete set in the p-dimensional Euclidian space is almost periodic, if the measure with the unite masses at points of the set is almost periodic in the weak sense. We propose to construct positive almost periodic ...
  • Kashu, A.I. (Algebra and Discrete Mathematics, 2010)
    For an arbitrary module M∈R-Mod the relation between the lattice Lch(RM) of characteristic (fully invariant) submodules of M and big lattice R-pr of preradicals of R-Mod is studied. Some isomorphic images of Lch(RM) in ...
  • Kulazhenko, Yu.I. (Algebra and Discrete Mathematics, 2010)
    In this paper new criteria of semi-commutativity and results on self-coincidence of an arbitrary point P in the terms of properties of vectors of n-ary groups are obtained.
  • Umar, A. (Algebra and Discrete Mathematics, 2010)
    Let Xn={1,2,⋯,n} and let α:Domα⊆Xn→Imα⊆Xn be a (partial) transformation on Xn. On a partial one-one mapping of Xn the following parameters are defined: the height of α is h(α)=|Imα|, the right [left] waist of α is ...
  • Lutsenko, I. (Algebra and Discrete Mathematics, 2010)
    A subset T of a group G with the identity e is called k-thin (k∈N) if |A∩gA| ≤ k, |A∩Ag| ≤ k for every g∈G, g≠e. We show that every infinite group G can be generated by some 2-thin subset. Moreover, if G is either Abelian ...
