Finitely $t$-valuative domains

Main Article Content

Gyu Whan Chang


Let $D$ be an integral domain with quotient field $K$. In \cite{cdl12}, the authors called $D$ a finitely valuative domain if, for each $0 \neq u \in K$, there is a saturated chain of rings $D = D_0 \subsetneq D_1 \subsetneq \cdots D_n = D[x]$, where $x = u$ or $u^{-1}$. They then studied some properties of finitely valuative domains. For example, they showed that the integral closure of a finitely valuative domain is a Pr\"ufer domain. In this paper, we introduce the notion of finitely $t$-valuative domains, which is the $t$-operation analog of finitely valuative domains, and we then generalize some properties of finitely valuative domains.
