 Overrings of the Kronecker function ring $Kr(D, *)$ of a Pr\"ufer $*$-multiplication domain $D$ Bull. Korean Math. Soc. 2009 Vol. 46, No. 5, 1013-1018 https://doi.org/10.4134/BKMS.2009.46.5.1013Printed September 1, 2009 Gyu Whan Chang University of Incheon Abstract : Let $*$ be an $e.a.b.$ star operation on an integrally closed domain $D$, and let $Kr(D,*)$ be the Kronecker function ring of $D$. We show that if $D$ is a P$*$MD, then the mapping $D_{\alpha} \mapsto Kr(D_{\alpha}, v)$ is a bijection from the set $\{D_{\alpha}\}$ of $*$-linked overrings of $D$ into the set of overrings of $Kr(D,v)$. This is a generalization of \cite[Proposition 32.19]{gilmer} that if $D$ is a Pr\"ufer domain, then the mapping $D_{\alpha} \mapsto Kr(D_{\alpha}, b)$ is a one-to-one mapping from the set $\{D_{\alpha}\}$ of overrings of $D$ onto the set of overrings of $Kr(D,b)$.
