Ideal containment in commutative rings

Let R be a commutative ring with identity. An ideal I of R is said to be a big ideal (respectively, an upper big ideal) if whenever Jn I (respectively, IJ), Jn In (respectively, In Jn) for every n ≥ 1; and R itself is a big ideal ring provided that every ideal of R is a big ideal. In this paper, we study the notions of big ideals, upper big ideals and big ideal rings in different contexts of commutative rings such us integrally closed domains, pullbacks and trivial ring extensions. We show that the notions of big and upper big ideals are completely different. The notion of big ideal is correlated to the notion of basic ideal and the notion of upper big ideal is correlated to the notion of C-ideals. We give a new characterization of Prüfer domains via big ideal domains and we characterize some particular cases of pullback rings that are big ideal domains. Also, we give some classes of big and upper big ideals in rings with zero-divisors via trivial ring extensions.
