  • Exact annihilating-ideal graph of commutative rings 

    LALCHANDANI, PREMKUMAR (University of Guilan, 2017-06-01)
    The rings considered in this article are commutative rings with identity $1neq 0$. The aim of this article is to define and study the exact annihilating-ideal graph of commutative rings. We discuss the interplay between ...

  • Good strongly regular relations on weak $Gamma$-(semi)hypergroups 

    Jafarpour, Morteza؛ Aghabozorgi, Hossien؛ Zare, Tahere (University of Guilan, 2017-06-01)
    In this paper first we introduce the notion of weak $Gamma$-(semi)hypergroups, next some classes of equivalence relations which are called good regular and strongly good regular relations are defined.  Then we investigate ...

  • Left I-quotients of band of right cancellative monoids 

    Ghroda, Nassraddin (University of Guilan, 2017-06-01)
    Let $Q$ be an inverse semigroup. A subsemigroup $S$ of $Q$ is a left I-order in $Q$ and $Q$ is a semigroup of left I-quotients of $S$ if every element $qin Q$ can be written as $q=a^{-1}b$ for some $a,bin S$. If we insist ...

  • A new branch of the logical algebra: UP-algebras 

    IAMPAN, Aiyared (University of Guilan, 2017-06-01)
    In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated ...

  • A Note on a graph associated to a commutative ring 

    Visweswaran, Subramanian؛ Parejiya, Jaydeep (University of Guilan, 2017-06-01)
    The rings considered in this article are commutative with identity. This article is motivated by the work on comaximal graphs of rings.  In this article, with any ring $R$, we associate an undirected graph denoted by $G(R)$, ...
