Abstract
Let be an integral domain and be a torsion-free commutative cancellative (additive) semigroup with identity element and quotient group . In this paper, we show that if char (resp., char), then is a weakly Krull domain if and only if is a weakly Krull UMT-domain, is a weakly Krull UMT-monoid, and is of type (resp., type except ). Moreover, we give arithmetical applications of this result.
