  • Modules which have a rad-supplement that is a direct summand in every extension 
    Türkmen, B.N.; Türkmen, E. (Algebra and Discrete Mathematics, 2018)
    In this paper, we introduce the concept of modules with the properties (RE) and (SRE), and we provide various properties of these modules. In particular,we prove that a semisimple module M is Rad-supplementing if and only ...
  • Characterization of regular convolutions 
    Sagi S. (Algebra and Discrete Mathematics, 2018)
    In this paper, we present a characterization of regular convolution.
  • Multiplicative orders of elements in Conway's towers of finite fields 
    Popovych, R. (Algebra and Discrete Mathematics, 2018)
    We give a lower bound on multiplicative orders of certain elements in defined by Conway towers of finite fields of characteristic 2 and also formulate a condition under that these elements are primitive.
  • Weak equivalence of representations of Kleinian 4-group 
    Plakosh, A. (Algebra and Discrete Mathematics, 2018)
    We give a classification of representations of the Kleinian 4-group up to weak equivalence.
  • Neighborhood-prime labeling of some product graphs 
    Patel, S.K.; Shrimali, N.P. (Algebra and Discrete Mathematics, 2018)
    We have introduced the concept of neighborhood-prime labeling and investigated it for paths, cycles, wheels and union of such graphs earlier. In this paper, we construct neighborhood-prime labelings for graphs that are ...
  • Closure operators in modules and adjoint functors, I 
    Kashu, A.I. (Algebra and Discrete Mathematics, 2018)
    In the present work the relations between the closure operators of two module categories are investigated in the case when the given categories are connected by two covariant adjoint functors H: R-Mod → S-Mod and T : S-Mod ...
  • Gram matrices and Stirling numbers of a class of diagram algebras, I 
    N. Karimilla Bi; Parvathi, M. (Algebra and Discrete Mathematics, 2018)
    In this paper, we introduce Gram matrices for the signed partition algebras, the algebra of Z₂-relations and the partition algebras. The nondegeneracy and symmetic nature of these Gram matrices are establised. Also, (s₁, ...
  • On application of linear algebra in classification cubic s-regular graphs of order 28p 
    Imani, A.; Mehdipoor, N.; Talebi, A.A. (Algebra and Discrete Mathematics, 2018)
    A graph is s-regular if its automorphism group acts regularly on the set of s-arcs. In this paper, by applying concept linear algebra, we classify the connected cubic s-regular graphs of order 28p for each s ≥ 1, and prime p.
  • Construction of a complementary quasiorder 
    Jakubíková-Studenovská, D.; Janičková, L. (Algebra and Discrete Mathematics, 2018)
    For a monounary algebra A = (A, f) we study the lattice QuordA of all quasiorders of A, i.e., of all reflexive and transitive relations compatible with f. Monounary algebras (A, f) whose lattices of quasiorders are ...
  • A way of computing the Hilbert series 
    Haider, A. (Algebra and Discrete Mathematics, 2018)
    Let S = K[x1, x2, . . . , xn] be a standard graded K-algebra for any field K. Without using any heavy tools of commutative algebra we compute the Hilbert series of graded S-module S/I, where I is a monomial ideal.
  • On the Fitting ideals of a multiplication module 
    Hadjirezaei, S.; Karimzadeh, S. (Algebra and Discrete Mathematics, 2018)
    In this paper, we characterize all finitely generated multiplication R-modules whose the first nonzero Fitting ideal of them is contained in only finitely many maximal ideals. Also, we prove that a finitely generated ...
  • Global outer connected domination number of a graph 
    Alishahi, M.; Mojdeh, D.A. (Algebra and Discrete Mathematics, 2018)
    In this paper we obtain some bounds for outer connected domination numbers and global outer connected domination numbers of graphs.
  • Periods of Tribonacci sequences and elliptic curves 
    AIt-Amrane, L.; Belbachir, H. (Algebra and Discrete Mathematics, 2018)
    We will study the periods of Tribonacci sequences associated to elliptic curves. This work is motivated by a paper of Coleman et al. who did it for classical Fibonacci sequences. We are convinced that similar results modulo ...
