  • 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.
  • Sagi S. (Algebra and Discrete Mathematics, 2018)
    In this paper, we present a characterization of regular convolution.
  • 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 ...
  • 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 ...
  • 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.
  • 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, ...
  • 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 ...
  • 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.
  • 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 ...
  • 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.
  • 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 ...
  • 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 ...
  • Plakosh, A. (Algebra and Discrete Mathematics, 2018)
    We give a classification of representations of the Kleinian 4-group up to weak equivalence.
