  • On nilpotent Lie algebras of derivations with large center 
    Sysak, K. (Algebra and Discrete Mathematics, 2016)
    Let K be a field of characteristic zero and A an associative commutative K-algebra that is an integral domain. Denote by R the quotient field of A and by W(A)=RDerA the Lie algebra of derivations on R that are products of ...
  • The groups whose cyclic subgroups are either ascendant or almost self-normalizing 
    Kurdachenko, L.A.; Pypka, A.A.; Semko, N.N. (Algebra and Discrete Mathematics, 2016)
    The main result of this paper shows a description of locally finite groups, whose cyclic subgroups are either almost self-normalizing or ascendant. Also, we obtained some natural corollaries of the above situation.
  • A survey of results on radicals and torsions in modules 
    Kashu, A.I. (Algebra and Discrete Mathematics, 2016)
    In this work basic results of the author on radicals in module categories are presented in a short form. Principal topics are: types of preradicals and their characterizations; classes of R-modules and sets of left ideals ...
  • Construction of self-dual binary [2²ⁿ,2²ⁿ⁻¹,2ⁿ]-codes 
    Hannusch, C.; Lakatos, P. (Algebra and Discrete Mathematics, 2016)
    The binary Reed-Muller code RM(m−n,m) corresponds to the n-th power of the radical of GF(2)[G], where G is an elementary abelian group of order 2m. Self-dual RM-codes (i.e. some powers of the radical of the previously ...
  • On classification of pairs of potent linear operators with the simplest annihilation condition 
    Bondarenko, V.M.; Tertychna, O.M.; Zubaruk, O.V. (Algebra and Discrete Mathematics, 2016)
    We study the problem of classifying the pairs of linear operators A,B (acting on the same vector space), when the both operators are potent and AB=0. We describe the finite, tame and wild cases and classify the indecomposable ...
  • Classification of L-cross-sections of the finite symmetric semigroup up to isomorphism 
    Bondar, E. (Algebra and Discrete Mathematics, 2016)
    Let Tn be the symmetric semigroup of full transformations on a finite set with n elements. In the paper we give a counting formula for the number of L-cross-sections of Tn and classify all L-cross-sections of Tn up to ...
  • An outer measure on a commutative ring 
    Dudzik, D.; Skrzyński, M. (Algebra and Discrete Mathematics, 2016)
    We show how to produce a reasonable outer measure on a commutative ring from a given measure on a family of prime ideals of this ring. We provide a few examples and prove several properties of such outer measures.
  • Normally ζ-reversible profinite groups 
    Cimetta, L.; Lucchini, A. (Algebra and Discrete Mathematics, 2016)
    We examine (finitely generated) profinite groups in which two formal Dirichlet series, the normal subgroup zeta function and the normal probabilistic zeta function, coincide; we call these groups normally ζ-reversible. We ...
  • Parafunctions of triangular matrices and m-ary partitions of numbers 
    Stefluk, S.; Zatorsky, R. (Algebra and Discrete Mathematics, 2016)
    Using the machinery of paradeterminants and parapermanents developed in [2] we get new relations for some number-theoretical functions natural argument that were studied in [3].
  • Co-intersection graph of submodules of a module 
    Mahdavi, L.A.; Talebi, Y. (Algebra and Discrete Mathematics, 2016)
    Let M be a unitary left R-module where R is a ring with identity. The co-intersection graph of proper submodules of M, denoted by Ω(M), is an undirected simple graph whose the vertex set V(Ω) is a set of all non-trivial ...
  • Alfred Lvovich Shmelkin (12.06.1938 — 22.12.2015) 
    Автор відсутній (Algebra and Discrete Mathematics, 2016)
    With deep sorrow and regret we learnt about the death on December 22, 2015 of our colleague, Alfred Lvovich Shmelkin, a prominent algebraist, Honoured Professor of Lomonosov Moscow State University and member of ADM editorial ...
