### On Zero-divisor Graphs Whose Cores Contain no Rectangles

• Mathematics
• 2011
This paper answers a question of Lu and Wu: How can one characterize the zero-divisor graphs which contain no rectangles? We prove that a graph which contains no rectangles is the zero-divisor graph

### Minimal prime ideals and cycles in annihilating-ideal graphs

• Mathematics
• 2013
Let R be a commutative ring with identity and A(R) be the set of ideals with non-zero annihilator. The annihilating-ideal graph of R is defined as the graph AG(R) with the vertex set A(R)∗ = A(R)\{0}

### SOME RESULTS ON THE INTERSECTION GRAPHS OF IDEALS OF RINGS

• Mathematics
• 2013
Let R be a ring with unity and I(R)* be the set of all nontrivial left ideals of R. The intersection graph of ideals of R, denoted by G(R), is a graph with the vertex set I(R)* and two distinct

### On realizing zero-divisor graphs of po-semirings

• Mathematics
• 2011
In this paper, we determine bipartite graphs and complete graphs with horns, which are realizable as zero-divisor graphs of po-semirings. As applications, we classify commutative rings $R$ whose

### Some Results on Intersection Graphs of Ideals of Commutative Rings

The rings considered in this article are commutative with identity which admit at least one nonzero proper ideal. Let R be a ring. Recall that the intersection graph of ideals of R, denoted by G(R),

### The Zero-Divisor Graph of a Commutative Semigroup: A Survey

• Mathematics
• 2017
Let S be a (multiplicative) commutative semigroup with 0. Associate to S a (simple) graph G(S) with vertices the nonzero zero-divisors of S, and two distinct vertices x and y are adjacent if and only

### The Annihilating-Ideal Graph of a Commutative Ring with Respect to an Ideal

• Mathematics
• 2014
For a commutative ring R with identity, the annihilating-ideal graph of R, denoted 𝔸𝔾(R), is the graph whose vertices are the nonzero annihilating ideals of R with two distinct vertices joined by

### The Zero-Divisor Graphs Which Are Uniquely Determined By Neighborhoods

• Mathematics
• 2007
A nonempty simple connected graph G is called a uniquely determined graph, if distinct vertices of G have distinct neighborhoods. We prove that if R is a commutative ring, then Γ(R) is uniquely

### The zero-divisor graph of a commutative semigroup

• Mathematics
• 2002
An undirected graph Γ(S) is associated to each commutative multiplicative semigroup S with 0. The vertices of the graph are labeled by the nonzero zero-divisors of S , and two vertices x,y are

### A New Graph Structure of Commutative Semigroups

• Mathematics
• 2005
AbstractIn this paper, a new zero-divisor graph $\overline{\G}(S)$ is defined and studied for a commutative semigroup $S$ with zero element. The properties and the structure of the graph are studied;
