Abstract

Let D be an integral domain and let F be a set of prime ideals of D. We say that D is an F-IFC domain if D = ∩P∈FDP where the intersection has finite character and for P, Q ∈ F there is no nonzero prime ideal contained in P ∩ Q. Examples of F-IFC domains include h-local do-mains (F = Max(D)), Noetherian domains in which grade-one primes have height one, and independent rings of Krull type. Using star operations we give several characterizations of F-IFC domains.
