  • On noncommutative bounded factorization domains and prime rings
    Bell, Jason P. ...
    A ring has bounded factorizations if every cancellative nonunit ▫$a \in R$▫ can be written as a product of atoms and there is a bound ▫$\lambda (a)$▫ on the lengths of such factorizations. The ... bounded factorization property is one of the most basic finiteness properties in the study of non-unique factorizations. Every commutative noetherian domain has bounded factorizations, but it is open whether such a result holds in the noncommutative setting. We provide sufficient conditions for a noncommutative noetherian prime ring to have bounded factorizations. Moreover, we construct a (noncommutative) finitely presented semigroup algebra that is an atomic domain but does not satisfy the ascending chain condition on principal right or left ideals (ACCP), whence it does not have bounded factorizations.
