Abstract

In this introductory chapter we introduce several variations on factoring ideals into finite products of prime ideals. For example, a domain has radical factorization if each ideal can be factored as a finite product of radical ideals. Such domains are also known as SP-domains. A domain has weak factorization if each nonzero nondivisorial ideal can be factored as the product of its divisorial closure and a finite product of maximal ideals. If one can always have such a factorization where the maximal ideals are distinct, then the domain has strong factorization. Finally, a domain has pseudo-Dedekind factorization if each nonzero noninvertible ideal can be factored as the product of an invertible ideal and a finite product of pairwise comaximal prime ideals with at least one prime in the product. In addition, if each invertible ideal has such a factorization, then the domain has strong pseudo-Dedekind factorization.
