Star-invertible ideals of integral domains

Gyu Whan Chang, Jeanam Park (2003)

Bollettino dell'Unione Matematica Italiana

Similarity:

Let be a star-operation on R and s the finite character star-operation induced by . The purpose of this paper is to study when = v or s = t . In particular, we prove that if every prime ideal of R is -invertible, then = v , and that if R is a unique -factorable domain, then R is a Krull domain.

Ideal class (semi)groups and atomicity in Prüfer domains

Richard Erwin Hasenauer (2021)

Czechoslovak Mathematical Journal

Similarity:

We explore the connection between atomicity in Prüfer domains and their corresponding class groups. We observe that a class group of infinite order is necessary for non-Noetherian almost Dedekind and Prüfer domains of finite character to be atomic. We construct a non-Noetherian almost Dedekind domain and exhibit a generating set for the ideal class semigroup.
