More on the Annihilator-Ideal Graph of a Commutative Ring

M. J. Nikmehr, S. M. Hosseini

Let $R$ be a commutative ring with identity and $A (R)$ be the set of ideals of $R$ with non-zero annihilator. The annihilator-ideal graph of $R$ , denoted by $A_{I} (R)$ , is…

When the Annihilator Graph of a Commutative Ring Is Planar or Toroidal?

Mohammad Javad Nikmehr, Reza Nikandish, Moharam Bakhtyiari

Let $R$ be a commutative ring with identity, and let $Z (R)$ be the set of zero-divisors of $R$ . The annihilator graph of $R$ is defined as the undirected graph $A G (R)$ with the ver…
