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} and two distinct vertices I and J are adjacent if and only if IJ = 0. In this paper, we study some connections between the graph theoretic properties of this graph and some algebraic properties of a commutative ring. We prove that if AG(R) is a tree, then either AG(R) is a star graph or a path of… 
The principal ideal subgraph of the annihilating-ideal graph of commutative rings
Let R be a commutative ring with identity and A(R) be the set of ideals of R with non-zero annihilators. In this paper, we first introduce and investigate the principal ideal subgraph of the
The spectrum subgraph of the annihilating-ideal graph of a commutative ring
In this paper we introduce and study the spectrum graph of a commutative ring R, denoted by 𝔸𝔾s(R), that is, the graph whose vertices are all non-zero prime ideals of R with non-zero annihilator
On rings whose annihilating-ideal graphs are blowups of a class of Boolean graphs ∗
For a finite or an infinite set X, let 2 be the power set of X. A class of simple graph, called strong Boolean graph, is defined on the vertex set 2 \ {X, ∅}, with M adjacent to N if M ∩ N = ∅. In

For a finite or an infinite set X, let 2 be the power set of X. A class of simple graph, called strong Boolean graph, is defined on the vertex set 2 \ {X, ∅}, with M adjacent to N if M ∩ N = ∅. In
On the crosscap of the annihilating-ideal graph of a commuta tive ring
Let R be a non-domain commutative ring with identity and A(R) be the set of non-zero ideals with non-zero annihilators. We call an ideal I1 of R, an annihilating-ideal if there exists a non-zero
The annihilating-submodule graph of modules over commutative rings II
Let M be a module over a commutative ring R. The annihilating-submodule graph of M, denoted by AG(M), is a simple graph in which a non-zero submodule N of M is a vertex if and only if there exists a
A new graph associated to a commutative ring
TLDR
It is shown that ΩR∗ is a connected graph with diam(ΩR ∼3) ≤ 3 unless R is isomorphic to a direct product of two fields and all commutative rings R with at least two maximal ideals for which Ω R∗ are planar are characterized.
The Annihilating-Ideal Graph of a Ring
Let $S$ be a semigroup with $0$ and $R$ be a ring with $1$. We extend the definition of the zero-divisor graphs of commutative semigroups to not necessarily commutative semigroups. We define an
The Co-annihilating-ideal Graphs of Commutative Rings
Abstract Let $R$ be a commutative ring with identity. The co-annihilating-ideal graph of $R$ , denoted by ${{\mathcal{A}}_{R}}$ , is a graph whose vertex set is the set of all non-zero proper ideals
