Let R be a commutative ring with nonzero identity, let I(R) be the set of all ideals of R and δ: I(R) → I(R) be a function. Then δ is called an expansion function of ideals of R if whenever L, I, J are ideals of R with J ⊆ I, we have L ⊆ δ(L) and δ(J) ⊆ δ(I). In this paper, we present the concept of δ(0)-ideals in commutative rings. A proper ideal I of R is called a δ(0)-ideal if whenever a, b ∈ R with ab ∈ I and a ∉ δ(0), we have b ∈ I. Our purpose is to extend the concept of n-ideals to δ(0)-ideals of commutative rings. Then we investigate the basic properties of δ(0)-ideals and also, we give many examples about δ(0)-ideals.
