چکیده
|
Let r be a commutative ring with identity. we use φ(r) to denote the comaximal ideal graph. the vertices of φ(r) are proper ideals of r which are not contained in the jacobson radical of r, and two vertices i and j are adjacent if and only if i+j=r. in this paper we show some properties of this graph together with planarity of line graph associated to φ(r).
