Some remarks on Prüfer $⋆$ --multiplication domains and class groups

David F. Anderson, Marco Fontana, Muhammad Zafrullah

Let $D$ be an integral domain with quotient field $K$ and let $X$ be an indeterminate over $D$ . Also, let $T := {T_{λ} ∣ λ \in Λ}$ be a defining family of qu…

The patch topology and the ultrafilter topology on the prime spectrum of a commutative ring

Marco Fontana, K. Alan Loper

Let R be a commutative ring and let Spec(R) denote the collection of prime ideals of R. We define a topology on Spec(R) by using ultrafilters and demonstrate that this topology is…

Uppers to zero and semistar operations in polynomial rings

Gyu Whan Chang, Marco Fontana

Given a stable semistar operation of finite type $⋆$ on an integral domain $D$ , we show that it is possible to define in a canonical way a stable semistar operation of finite t…
