  • A horizontal mesh algorithm for posets with positive Tits form 
    Kaniecki, M.; Kosakowska, J.; Malicki, P.; Marczak, G. (Algebra and Discrete Mathematics, 2016)
  • 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 ...
  • Amply (weakly) Goldie-Rad-supplemented modules 
    Mutlu, F.T. (Algebra and Discrete Mathematics, 2016)
    Let R be a ring and M be a right R-module. We say a submodule S of M is a \textit{(weak) Goldie-Rad-supplement} of a submodule N in M, if M=N+S, (N∩S≤Rad(M)) N∩S≤Rad(S) and Nβ∗∗S, and M is called amply (weakly) ...
  • An amalgamation property for metric spaces 
    Ivanov, A.; Majcher-Iwanow, B. (Algebra and Discrete Mathematics, 2016)
    In this paper we show that sufficiently similar finite metric spaces can be amalgamated so that the distance between them is sufficiently small.
  • 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.
  • 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 ...
  • Automorphisms of the endomorphism semigroup of a free commutative g-dimonoid 
    Zhuchok, Y.V. (Algebra and Discrete Mathematics, 2016)
    We determine all isomorphisms between the endomorphism semigroups of free commutative g-dimonoids and prove that all automorphisms of the endomorphism semigroup of a free commutative g-dimonoid are quasi-inner.
  • 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 ...
  • 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 ...
  • 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 ...
  • Extended star graphs 
    Gutierrez, M.; Tondato, S.B. (Algebra and Discrete Mathematics, 2016)
    Chordal graphs, which are intersection graph of subtrees of a tree, can be represented on trees. Some representation of a chordal graph often reduces the size of the data structure needed to store the graph, permitting the ...
  • Factorization of elements in noncommutative rings, I 
    Facchini, A.; Fassina, M. (Algebra and Discrete Mathematics, 2016)
    We extend the classical theory of factorization in noncommutative integral domains to the more general classes of right saturated rings and right cyclically complete rings. Our attention is focused, in particular, on the ...
  • Finite local nearrings with split metacyclic additive group 
    Raievska, I.I.; Raievska, M.I.; Sysak, Y.P. (Algebra and Discrete Mathematics, 2016)
    In the paper the split metacyclic groups which are the additive groups of finite local nearrings are classified
  • Free n-dinilpotent doppelsemigroups 
    Zhuchok, A.V.; Demko, M. (Algebra and Discrete Mathematics, 2016)
    A doppelalgebra is an algebra defined on a vector space with two binary linear associative operations. Doppelalgebras play a prominent role in algebraic K-theory. In this paper we consider doppelsemigroups, that is, sets ...
  • Generalization of primal superideals 
    Jaber, A. (Algebra and Discrete Mathematics, 2016)
    Let R be a commutative super-ring with unity 16= 0. A proper super ideal of R is a super ideaI of R such that I 6=R.Letφ:I(R)→I(R)∪ {∅}be any function, where I(R) denotes the set of all proper super ideals of R. A homogeneous ...
  • Generalizations of semicoprime preradicals 
    Darani, A.Y.; Mostafanasab, H. (Algebra and Discrete Mathematics, 2016)
    This article introduces the notions quasi-co-n-absorbing preradicals and semi-co-n-absorbing preradicals, generalizing the concept of semicoprime preradicals. We study the concepts quasi-co-n-absorbing submodules and ...
  • Generalized norms of groups 
    Drushlyak, M.G.; Lukashova, T.D.; Lyman, F.M. (Algebra and Discrete Mathematics, 2016)
    In this survey paper the authors specify all the known findings related to the norms of the group and their generalizations. Special attention is paid to the analysis of their own study of different generalized norms, ...
  • Groups satisfying certain rank conditions 
    Dixon, M.R.; Kurdachenko, L.A.; Pypka, A.A.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2016)
    This is a survey of a number of recent results concerned with groups whose subgroups satisfy certain rank conditions.
  • Hamming distance between the strings generated by adjacency matrix of a graph and their sum 
    Ganagi, A.B.; Ramane, H.S. (Algebra and Discrete Mathematics, 2016)
    Let A(G) be the adjacency matrix of a graph G. Denote by s(v) the row of the adjacency matrix corresponding to the vertex v of G. It is a string in the set Zn2 of all n-tuples over the field of order two. The Hamming ...
  • Indecomposable and irreducible t-monomial matrices over commutative rings 
    Bondarenko, V.M.; Bortos, M.; Dinis, R.; Tylyshchak, A. (Algebra and Discrete Mathematics, 2016)
    We introduce the notion of the defining sequence of a permutation indecomposable monomial matrix over a commutative ring and obtain necessary conditions for such matrices to be indecomposable or irreducible in terms ...
