Let D be a domain with quotient 7eld K and let Int(D) be the ring of integer-valued polynomials\ud{f ∈ K[X ] | f(D) ⊆ D}. We give conditions on D so that the ring Int(D) is a Strong\udMori domain. In particular, we give a complete characterization in the case that the conductor\ud(D :D) is nonzero, where D is the integral closure of D. We also show that when D is quasilocal\udwith Int(D) =D[X] or D is Noetherian, Int(D) is a Strong Mori domain if and only if Int(D)\udis Noetherian.
