  • Labelling matrices and index matrices of a graph structure 
    Dinesh, T.; Ramakrishnan, T.V. (Algebra and Discrete Mathematics, 2013)
    The concept of graph structure was introduced by E. Sampathkumar in 'Generalised Graph Structures', Bull. Kerala Math. Assoc., Vol 3, No.2, Dec 2006, 65-123. Based on the works of Brouwer, Doob and Stewart, R.H. Jeurissen ...
  • Lattice groups 
    Kurdachenko, L.A.; Yashchuk, V.S.; Subbotin, I.Y. (Algebra and Discrete Mathematics, 2015)
    In this paper, we introduce some algebraic structure associated with groups and lattices. This structure is a semigroup and it appeared as the result of our new approach to the fuzzy groups and L-fuzzy groups where L is a ...

    Kurdachenko, L.A.; Yashchuk, V.S.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2015)
    In this paper, we introduce some algebraic struc-ture associated with groups and lattices. This structure is a semi-group and it appeared as the result of our new approach to thefuzzy groups andL-fuzzy groups whereLis a ...
  • Lattice rings: an interpretation of L-fuzzy rings as habitual algebraic structures 
    Kurdachenko, L.A.; Ya, I.; Yashchuk, V.S. (Algebra and Discrete Mathematics, 2017)
    In this paper, we introduce some algebraic structure associated with rings and lattices. It appeared as the result of our new approach to the fuzzy rings and L-fuzzy rings where L is a lattice. This approach allows us to ...
  • Lattices of classes of groupoids with one-sided quasigroup conditions 
    Galuszka, J. (Algebra and Discrete Mathematics, 2010)
    It is shown that two classes of groupoids satisfying certain one-sided quasigroup conditions, namely the classes of one-sided torsion groupoids and of one-sided finite exponent groupoids, are complete lattices, both ...
  • Lattices of partial sums 
    Chiaselotti, G.; Gentile, T.; Oliverio, P.A. (Algebra and Discrete Mathematics, 2014)
    In this paper we introduce and study a class of partially ordered sets that can be interpreted as partial sums of indeterminate real numbers. An important example of these partially ordered sets, is the classical Young ...
  • Lattices of topologies of algebraic systems 
    Arnautov, V.I.; Filippov, K.M. (Algebra and Discrete Mathematics, 2006)
    The article is based on the report, which was delivered on a plenary sitting on the 5th International Algebraic Conference in the Ukraine (Odessa, July, 2005) and is a survey of the results on the lattices of topologies ...
  • L-cross-sections of the finite symmetric semigroup 
    Bondar, E. (Algebra and Discrete Mathematics, 2014)
    In the present paper we give the description of all L-cross-sections of the finite symmetric semigroup.
  • Leibniz algebras with absolute maximal Lie subalgebras 
    Biyogmam, G.R.; Tcheka, C. (Algebra and Discrete Mathematics, 2020)
    A Lie subalgebra of a given Leibniz algebra is said to be an absolute maximal Lie subalgebra if it has codimension one. In this paper, we study some properties of non-Lie Leibniz algebras containing absolute maximal Lie ...
  • Length functions for semigroup embeddings 
    Davis, T.C. (Algebra and Discrete Mathematics, 2010)
    Following the work done in [O] for groups, we describe, for a given semigroup S, which functions l:S→N can be realized up to equivalence as length functions g↦|g|H by embedding S into a finitely generated semigroup H. We ...
  • Length of the inverse symmetric semigroup 
    Ganyushkin, O.; Livinsky, I. (Algebra and Discrete Mathematics, 2011)
    The length of the lattice of subsemigroups of the inverse symmetric semigroup ISn is calculated.
  • Leonid A. Kurdachenko (dedicated to 70th Birthday) 
    Автор відсутній (Algebra and Discrete Mathematics, 2020)
    Leonid A. Kurdachenko is definitely one of the most productive group theorists. His list of publications consists of more than 250 journal articles published in major mathematics journals in many countries including Ukraine, ...
  • Leonid Aleksandrovich Shemetkov 
    Автор відсутній (Algebra and Discrete Mathematics, 2013)
    Ukrainian algebraists with keen sorrow have learned about the death of our colleague, a prominent algebraist and a tremendously efficient science manager of the Republic of Belarus Leonid Aleksandrovich Shemetkov. Leonid ...
  • Leonid Shemetkov. His entire life devotion 
    Skiba, A.N.; Monakhov, V.S.; Selkin, M.V.; Vorob’ev, N.T.; Semenchuk, V.N.; Vasil’ev, A.F. (Algebra and Discrete Mathematics, 2013)
    It is given a short scientific biography of Professor L.A. Shemetkov.
  • Lie algebras associated with quadratic forms and their applications to Ringel-Hall algebras 
    Kosakowska, J. (Algebra and Discrete Mathematics, 2008)
    We define and investigate Lie algebras associated with quadratic forms. We also present their connections with Lie algebras and Ringel-Hall algebras associated with representation directed algebras.
  • Lie algebras of derivations with large abelian ideals 
    Klymenko, I.S.; Lysenko, S.V.; Petravchuk, A. (Algebra and Discrete Mathematics, 2019)
    We study subalgebras L of rank m over R of the Lie algebra Wn(K) with an abelian ideal I ⊂ L of the same rank m over R.
  • Lie and Jordan structures of differentially semiprime rings 
    Artemovych, O.D.; Lukashenko, M.P. (Algebra and Discrete Mathematics, 2015)
    Properties of Lie and Jordan rings (denoted respectively by RL and RJ) associated with an associative ring R are discussed. Results on connections between the differentially simplicity (respectively primeness, semiprimeness) ...
  • Linear cellular automata: Garden of Eden Theorem, L-surjunctivity and group rings 
    Ceccherini-Silberstein, T.; Coornaert, M. (Algebra and Discrete Mathematics, 2006)

  • Linear groups saturated by subgroups of finite central dimension 
    Semko, N.N.; Skaskiv, L.V.; Yarovaya, O.A. (Algebra and Discrete Mathematics, 2020)
    Let F be a field, A be a vector space over F and G be a subgroup of GL(F,A). We say that G has a dense family of subgroups, having finite central dimension, if for every pair of subgroups H, K of G such that H ≤ K and H ...
  • Local embeddability 
    Belegradek, O. (Algebra and Discrete Mathematics, 2012)
    For an arbitrary class of algebraic structures we consider a notion of a structure locally embeddable to structures of the class. This generalizes the notion of a group locally embeddable to finite groups studied by Vershik ...
