  • Classification of inverse semigroups generated by two-state partially defined invertible automata over the two-symbol alphabet 
    Slupik, J.K. (Algebra and Discrete Mathematics, 2006)
    The classification of inverse semigroups generated by two-state partially defined invertible automata over a twosymbol alphabet is investigated. Two presentations of such semigroups are given. The structures of these ...
  • Cohomology of the categorical at zero semigroups 
    Kostin, A. (Algebra and Discrete Mathematics, 2006)
    In this article we consider the relation between 0−cohomology and extended Eilenberg-MacLane cohomology of categorical at zero semigroups.
  • Groups which are isomorphic to their subgroups with non-modular subgroup lattice 
    De Falco, M.; Musella, C. (Algebra and Discrete Mathematics, 2006)
    This paper describes the structure of groups G containing proper subgroups with non-modular subgroup lattice and such that all such subgroups are isomorphic to G.
  • Isolated and nilpotent subsemigroups in the variants of ISn 
    Tsyaputa, G. (Algebra and Discrete Mathematics, 2006)
    All isolated, completely isolated, and nilpotent subsemigroups in the semigroup ISn of all injective partial transformations of an n-element set, considered as a semigroup with a sandwich multiplication are described.
  • Isomorphisms of Cayley graphs of surface groups 
    Bozejko, M.; Dykema, K.; Lehner, F. (Algebra and Discrete Mathematics, 2006)
    A combinatorial proof is given for the fact that the Cayley graph of the fundamental group Γg of the closed, orientable surface of genus g ≥ 2 with respect to the usual generating set is isomorphic to the Cayley graph ...
  • On automorphism groups of some modules 
    Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2006)
    In this paper we investigated ZG-module A, where G is either nilpotent or soluble group of infinite special rank. It is described the construction of these modules in the case, if for any proper subgroup H of infinite ...
  • Strongly orthogonal and uniformly orthogonal many-placed operations 
    Belyavskaya, G.; Mullen, G.L. (Algebra and Discrete Mathematics, 2006)
    In [3] we have studied connection between orthogonal hypercubes and many-placed (d-ary) operations, have considered different types of orthogonality and their relationships. In this article we continue study of orthogonality ...
  • Uncountably many non-isomorphic nilpotent real n-Lie algebras 
    Stitzinger, E.; Williams, M.P. (Algebra and Discrete Mathematics, 2006)
    There are an uncountable number of non-isomorphic nilpotent real Lie algebras for every dimension greater than or equal to 7. We extend an old technique, which applies to Lie algebras of dimension greater than or equal ...
