Abstract
Let R be an integral domain with quotient field L. An overring T of R is t-linked over R if I -1 = R implies that (T : IT) = T for each finitely generated ideal I of R. Let O t (R) denotes the set of all t-linked overrings of R and O(R) the set of all overrings of R. The purpose of this paper is to study some finiteness conditions on the set O t (R). Particularly, we prove that if O t (R) is finite, then so is O(R) and O t (R) = O(R), and if each chain of t-linked overrings of R is finite, then each chain of overrings of R is finite. This yields that the t-linked approach is more efficient than the Gilmer's treatment (Proc Am Math Soc 131:2337-2346, 2002). We also examine the finiteness conditions in some Noetherian-like settings such as Mori domain, quasicoherent Mori domain, Krull domain, etc. We establish a connection between O t (R) and the set of all strongly divisorial ideals of R and we conclude by a characterization of domains R that are t-linked under all their overrings.
