The *-Nagata Ring of almost Prüfer *-multiplication Domains Lim, Jung Wook;
Let D be an integral domain with quotient field K, denote the integral closure of D in K and * be a star-operation on D. In this paper, we study the *-Nagata ring of AP*MDs. More precisely, we show that D is an AP*MD and is a root extension if and only if the *-Nagata ring is an AB-domain, if and only if is an AP-domain. We also prove that D is a P*MD if and only if D is an integrally closed AP*MD, if and only if D is a root closed AP*MD.
