“…Let D be an integrally closed integral domain with quotient field K. where c(f ) is the content of f and ∧ ∆ is the semistar operation defined in Section 2.4. See [15,Chapter 32] or [13] for general properties of Kronecker function rings.…”

Let V be a minimal valuation overring of an integral domain D and let Zar(D) be the Zariski space of the valuation overrings of D. Starting from a result in the theory of semistar operations, we prove a criterion under which the set Zar(D) \ {V } is not compact. We then use it to prove that, in many cases, Zar(D) is not a Noetherian space, and apply it to the study of the spaces of Kronecker function rings and of Noetherian overrings.

“…The ring D X N v is a nice generalization of the Nagata ring construction and considered by Kang [17]. We call D X N v the (t-)Nagata ring of D. When no ambiguity may arise, D X N v is simply called the Nagata ring of D. For more on D X and D X N v , PRÜFER-LIKE DOMAINS AND THE NAGATA RING 4247 the reader can be referred to Fontana and Loper's interesting survey article [12] or [11]. In this article, we study when D X and D X N v become globalized pseudovaluation domains.…”

A subring A of a Prüfer domain B is a globalized pseudo-valuation domain (GPVD) if (i) A → B is a unibranched extension and (ii) there exists a nonzero radical ideal I, common toA and B such that each prime ideal of A (resp., B) containing I is maximal in A (resp., B). Let D be an integral domain, X be an indeterminate over D, c f be the ideal of D generated by the coefficients of a polynomial f ∈ D X , N = f ∈ D X c f = D , and N v = f ∈ D X c f −1 = D . In this article, we study when the Nagata ring D X N (more generally, D X N v ) is a GPVD. To do this, we first use the so-called t-operation to introduce the notion of t-globalized pseudo-valuation domains (t-GPVDs). We then prove that D X N v is a GPVD if and only if D is a t-GPVD and D X N v has Prüfer integral closure, if and only if D X is a t-GPVD, if and only if each overring of D X N v is a GPVD. As a corollary, we have that D X N is a GPVD if and only if D is a GPVD and D has Prüfer integral closure. We alsogive several examples of integral domains D such that D X N v is a GPVD.

Abstract. We consider properties and applications of a new topology, called the Zariski topology, on the space SStar(A) of all the semistar operations on an integral domain A. We prove that the set of all overrings of A, endowed with the classical Zariski topology, is homeomorphic to a subspace of SStar(A). The topology on SStar(A) provides a general theory, through which we see several algebraic properties of semistar operation as very particular cases of our construction. Moreover, we show that the subspace SStar f (A) of all the semistar operations of finite type on A is a spectral space.
