On the Set of $t$-Linked Overrings of an integral domain
Abstract
et be an integral domain with quotient field . An overring of is -linked over if implies that for each finitely generated ideal of . Let denotes the set of all -linked overrings of and the set of all overrings of . The purpose of this paper is to study some finiteness conditions on the set . Particularly, we prove that if is finite, then so is and , and if each chain of -linked overrings of is finite, then each chain of overrings of is finite. This yields that the -linked approach is more efficient than the Gilmer's treatment in \cite{G1}. 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 and the set of all strongly divisorial ideals of and we conclude by a characterization of domains that are -linked under all their overrings.
