  • The generalized total graph of modules respect to proper submodules over commutative rings. 

    Tohidi, N. K.؛ Esmaeili Khalil Saraei, Fatemeh؛ Jalili, S. A. (University of Guilan, 2014-06-01)
    Let $M$ be a module over a commutative ring $R$ and let $N$ be a proper submodule of $M$. The total graph of $M$ over $R$ with respect to $N$, denoted by $T(Gamma_{N}(M))$, have been introduced and studied in [2]. In this ...

  • Asymptotic behaviour of associated primes of monomial ideals with combinatorial applications 

    Nasernejad, M. (University of Guilan, 2014-06-01)
    Let  $R$ be a commutative Noetherian ring and $I$ be an ideal of $R$. We say that $I$ satisfies the persistence property if  $mathrm{Ass}_R(R/I^k)subseteq mathrm{Ass}_R(R/I^{k+1})$ for all positive integers $kgeq 1$, which ...

  • Some results on Noetherian semigroup 

    Estaji, A. A.؛ Estaji, A. As. (University of Guilan, 2014-06-01)
    In this paper we study some results on Noetherian semigroups. We  show that if  $S_S$ is an  strongly  faithful $S$-act and $S$ is a duo weakly Noetherian, then we have the following.

  • Primal strong co-ideals in semirings 

    Ebrahimi Atani, S.؛ Dolati Pish Hesari, S.؛ Khoramdel, Mehdi (University of Guilan, 2014-06-01)
    In this paper, we introduce the notion of primal strong co-ideals and give some results involving them. It is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. Also ...

  • Cubic symmetric graphs of orders $36p$ and $36p^{2}$ 

    Alaeiyan, M.؛ Pourmokhtar, L.؛ Hosseinpoor, M. K. (University of Guilan, 2014-06-01)
    A graph is textit{symmetric}, if its automorphism group is transitive on the set of its arcs. In this paper, we  classifyall the connected cubic symmetric  graphs of order $36p$  and $36p^{2}$, for each prime $p$, of which ...
