Factorization in almost Dedekind domain

Gyu Whan Chang, Hyun Seung Choi

Let $F$ be a field, $p$ a prime number, $X$ an indeterminate over $F$ , $D_{n} = F [X^{\frac{1}{p ^{n}}}, X^{- \frac{1}{p ^{n}}}]$ for each integer $n \geq 0$ and $D = \bigcup\limits_{n\in\mat…

Valuation Ideal Factorization Domains

Gyu Whan Chang, Andreas Reinhart

An integral domain $D$ is a {\em valuation ideal factorization domain} (VIFD) if each nonzero principal ideal of $D$ can be written as a finite product of valuation ideals. Clearly…
