On Commuting graphs of triangular rings

Hassan Cheraghpour, Nader M. Ghosseiri, Madineh Jafari +1

Let $R$ be a noncommutative ring with identity. The commuting graph of $R$ , denoted by $Γ (R)$ , is a graph with vertex set $R ∖ Z (R)$ , and two vertices $a$ , $b$ are adjacent…

On Jordan superderivations and Jordan super-biderivations of trivial extensions and triangular matrix rings

Hassan Cheraghpour, Madineh Jafari

Triangular matrix rings are example of trivial extensions. In this article we describe the Jordan superderivations of the trivial extensions and upper triangular matrix rings. We d…

Sequentially Cohen-Macaulay matroidal ideals

Madineh Jafari, Amir Mafi, Hero Saremi

Let $R = K [x_{1}, ..., x_{n}]$ be the polynomial ring in $n$ variables over a field $K$ and let $J$ be a matroidal ideal of degree $d$ in $R$ . In this paper, we study the class of sequenti…
