  • Some categorical structures of generalized topologies in terms of monotone operators 

    Mohammadi Khorsand, Tahere؛ Mirhosseinkhani, Ghasem (Yazd University, 2020-02-01)
    In this paper, we give some generalized categories of topological spaces in terms of monotone operators and investigate some categorical properties of them. In particular, we present some equivalent categories of generalized ...

  • On the Schur pair of groups 

    Alizadeh Sanati, Mahboubeh (Yazd University, 2020-02-01)
    In this paper, it is shown that $ (mathcal{V}, mathfrak{X}) $ is a Schur pair if and only if the Baer-invariant of an $mathfrak{X}$-group with respect to $ mathcal{V}$ is an $mathfrak{X}$-group. Also, it is proved that a ...

  • Commutativity degree and non-commuting graph in finite groups and Mofang Loops and their relationships 

    Rezaie, Elhameh؛ Ahmadidelir, Karim؛ Tehranian, Abolfazl (Yazd University, 2020-02-01)
    Terms like commutativity degree, non-commuting graph and isoclinism are far well-known for much of the group theorists nowadays. There are so many papers about each of these concepts and also about their relationships in ...

  • $H$-supplemented modules and singularity 

    Moniri Hamzekolaee, Ali Reza (Yazd University, 2020-02-01)
    Let $M$ be a module over a ring $R$. We call $M$,$delta$-$H$-supplemented provided for every submodule $N$ of $M$ there is a direct summand $D$ of $M$ such that $M=N+X$ if and only if $M=D+X$ for every submodule $X$ of $M$ ...

  • The strongly annihilating-submodule graph of a module 

    Beyranvand, Reza؛ Farzi-Safarabadi, Ahadollah (Yazd University, 2020-02-01)
    In this paper, we define the notion of strongly annihilating-submodule graph of modules. This graph is a straightforward common generalization of the annihilating-submodule graph  and the annihilating-ideal graph. In ...

  • Finiteness of certain local cohomology modules 

    Dehghani-Zadeh, Fatemeh (Yazd University, 2020-02-01)
    Cofiniteness of the generalized local cohomology modules $H^{i}_{mathfrak{a}}(M,N)$ of two $R$-modules $M$ and $N$ withrespect to an ideal $mathfrak{a}$ is studied for some $i^{,}s$ witha specified property. ...

  • A new lower bound for cohomological dimension 

    Nazari, Alireza؛ Farokhi, Asghar (Yazd University, 2020-02-01)
    Let $(R,mathfrak{m})$ be a Noetherian local ring, $M$ a finitely generated $R$-module, and $mathfrak{a}$ an ideal of $R$. We define the $mathfrak{a}$-minimum dimension $d(mathfrak{a},M)$ of $M$ by $$d(mathfrak{a},M)=Min{dim ...

  • Cofinitely weak generalized $delta$-supplemented modules 

    Talaee, Behnam (Yazd University, 2020-02-01)
    We will study modules whose cofinite submodules have weak generalized-$delta$-supplements.  We attempt to investigate some properties of cofinitely weak generalized $delta$-supplemented modules.  We will prove for a module ...
