Abstract

It is well known that an integral domain $D$ is a UFD if and only if every nonzero prime ideal of $D$ contains a nonzero principal prime. This is the so-called Kaplansky's theorem. In this paper, we give this type of characterizations of a graded P$v$MD (resp., G-GCD domain, GCD domain, B\'ezout domain, valuation domain, Krull domain, $\pi$-domain).

Keywords: Kaplansky-type theorem, upper to zero, prime (primary) element, graded P$v$MD, graded GCD domain, graded G-GCD domain, graded B\'ezout domain, graded valuation domain, graded Krull domain, graded $\pi$-domain
