  • The probability that the commutator equation [x,y]=g has solution in a finite group 

    Hashemi, Mansour؛ Pirzadeh, Mina؛ Gorjian, Shoja Ali (University of Guilan, 2019-12-01)
    Let G be a finite group. For gin G, an ordered pair $(x_1,y_1)in Gtimes G$ is called a solution of the commutator equation $[x,y]=g$ if $[x_1,y_1]=g$. We consider rho_g(G)={(x,y)| x,yin G, [x,y]=g}, then the probability ...

  • Finding a generator matrix of a multidimensional cyclic code 

    ANDRIAMIFIDISOA, Ramamonjy؛ LALASOA, Rufine؛ Rabeherimanana, Toussaint (University of Guilan, 2019-12-01)
    We generalize Sepasdar's method for finding a gene-rator matrix of two-dimensional cyclic codes to find a generating set and a linearly independent subset of a general multicyclic code. From these sets, a basis of the code ...

  • Characterization of ^ϕ-amenability and ^ϕ-module amenability of semigroup algebras 

    Grailo Tanha, Somayeh (University of Guilan, 2019-12-01)
    For every inverse semigroup $S$ with subsemigroup $E$ of idempotents, necessary and sufficient conditions are obtained for the semigroup algebra $l ^{1}(S)$  to be $hat{phi}$-amenable and $hat{phi}$-module amenable. Also, ...

  • Connections between graphs and Sheaves 

    SAGAR, PYLA؛ KISHORE, PHANI (University of Guilan, 2019-12-01)
    In this paper, we discussed a method to construct a global sheaf space using graphs via Maximal compatibility blocks (MCB's) and we proposed the correspondence between graphs and sheaves. Further we discussed the sheaf ...

  • Harary spectrum of generalized composition of graphs and Harary equienergetic graphs 

    Ramane, Harishchandra؛ Patil, Daneshwari؛ K, Ashoka؛ Parvathalu, B. (University of Guilan, 2019-12-01)
    The Harary spectrum of a connected graph $G$ is the collection of the eigenvalues of its Harary matrix. The Harary energy of a graph $G$ is the sum of absolute values of its Harary eigenvalues. Harary equitable partition ...

  • Semi n-absorbing ideals in the semiring $Bbb Z_{0+}$ 

    Chaudhari, J. N.؛ Suryawanshi, M. D.؛ Bonde, Dipak (University of Guilan, 2019-12-01)
    In this paper, all principal (m , n)-closed ideals and principal semi n-absorbing ideals in the semiring of non-negative integers are investigated.
