On the automorphism group of a possible symmetric $(81, 16, 3)$ design

A. Abdollahi, H. R. Maimani, R. Torabi

In this paper we study the automorphism group of a possible symmetric $(81, 16, 3)$ design.

Comaximal graph of commutative rings

Hamid Reza Maimani, Maryam Salimi, Asiyeh Sattari +1

Let $R$ be a commutative ring with identity. Let $Γ (R)$ be a graph with vertices as elements of $R$ , where two distinct vertices $a$ and $b$ are adjacent if and only if $R a + R b = R$ .…

Zero-divisor graphs of amalgamated duplication of a ring along an ideal

Hamid Reza Maimani, Siamak Yassemi

Let $R$ be a commutative ring with identity and let $I$ be an ideal of $R$ . Let $R ⋈ I$ be the subring of $R \times R$ consisting of the elements $(r, r + i)$ for $r \in R$ and $i\in…

Complete $r$ -partite zero-divisor graphs and coloring of commutative semigroups

Hamid Reza Maimani, Mojgan Mogharrab, Siamak Yassemi

For a commutative semigroup $S$ with 0, the zero-divisor graph of $S$ denoted by $Γ (S)$ is the graph whose vertices are nonzero zero-divisor of $S$ , and two vertices $x$ , $y$ are a…
