Abstract:Let D be an integral domain, D be the integral closure of D, and be a numerical semigroup with ގ 0 . Let t be the so-called t-operation on D. We will say that D is an AK-domain (resp., AUF-domain) if for each nonzero ideal ({a α }) of D, there exists a positive integer n = n({a α }) such that ({a n α }) t is t-invertible (resp., principal). In this paper, we study several properties of AK-domains and AUF-domains. Among other things, we show that if D ⊆ D is a bounded root extension, then D is an AK-domain (r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
