Abstract

Let R be a commutative ring with A ( R ) its set of annihilating-ideals. The extended annihilating-ideal graph of R, denoted by AG ¯ ( R ) , is an undirected graph with vertex set A ( R ) * = A ( R ) { 0 } and two vertices I 1 and I 2 are adjacent if and only if I 1 m I 2 n = 0 with I 1 m 0 and I 2 n 0 , for some positive integers m and n. In this paper, we first study some basic properties of AG ¯ ( R ) and then we investigate the relationship between the extended annihilating-ideal graph AG ¯ ( R ) , the annihilator-ideal graph A I ( R ) and the annihilating-ideal graph AG ( R ) of a commutative ring R.
