On the arithmetic of Krull monoids with infinite cyclic class group

[摘要] Let H be a Krull monoid with infinite cyclic class group G and let G(p) subset of G denote the set of classes containing prime divisors. We study under which conditions on G(p) some of the main finiteness properties of factorization theory - such as local tameness, the finiteness and rationality of the elasticity, the structure theorem for sets of lengths, the finiteness of the catenary degree, and the existence of monotone and near monotone chains of factorizations - hold in H. In many cases, we derive explicit characterizations. (c) 2010 Elsevier B.V. All rights reserved.
