چکیده
|
The annihilating-ideal graph of a commutative ring r with unity is defined as the graph ag(r) whose vertex set is the set of all non-zero ideals with non-zero annihilators and two distinct vertices i and j are adjacent if and only if ij=0. nikandish et.al. proved that ag(zn) is weakly perfect. in this short paper, we characterize n for which ag(zn) is perfect.
