On the Star Class Group of a Pullback

Marco Fontana, Mi Hee Park

For the domain $R$ arising from the construction $T, M, D$ , we relate the star class groups of $R$ to those of $T$ and $D$ . More precisely, let $T$ be an integral domain, $M$ a nonz…

Semistar invertibility on integral domains

Marco Fontana, Giampaolo Picozza

After the introduction in 1994, by Okabe and Matsuda, of the notion of semistar operation, many authors have investigated different aspects of this general and powerful concept. A…

Integral Domains whose Simple Overrings are Intersections of Localizations

Marco Fontana, Evan Houston, Thomas Lucas

Call a domain $R$ an sQQR-domain if each simple overring of $R$ , i.e., each ring of the form $R [u]$ with $u$ in the quotient field of $R$ , is an intersection of localizations of $R…

Semistar Dedekind Domains

Said El Baghdadi, Marco Fontana, Giampaolo Picozza

Let $D$ be an integral domain and $⋆$ a semistar operation on $D$ . As a generalization of the notion of Noetherian domains to the semistar setting, we say that $D$ is a $⋆$ …
