Abstract

Let RR be a commutative ring and A(R){\Bbb{A}}(R) be the set of ideals with non-zero annihilators. The annihilating-ideal graph of RR is defined as the graph AG(R){\Bbb{AG}}(R) with vertex set A(R)=A{(0)}{\Bbb{A}}(R)^*={\Bbb{A}}\setminus\{(0)\} such that two distinct vertices II and JJ are adjacent if and only if IJ=(0)IJ=(0). We characterize commutative Noetherian rings RR whose annihilating-ideal graphs have finite genus γ(AG(R))\gamma(\Bbb{AG}(R)). It is shown that if RR is a Noetherian ring such that 0<γ(AG(R))<0<\gamma(\Bbb{AG}(R))<\infty, then RR has only finitely many ideals.
