Abstract

An integral domain DD is called a finite factorization domain (FFD) if every nonzero nonunit element of DD has only finitely many non-associate divisors. In 1998, for an integral domain DD and a cancellative torsion-free monoid SS such that each nonzero element of its quotient group is of type (0,0,)(0,0, \ldots), Kim proved that the monoid domain D[S]D[S] is an FFD if and only if DD is an FFD and SS is an FFM. However, it is still open whether a monoid algebra K[S]K[S] is an FFD provided that SS is a reduced FFM. In this paper, we show that a Puiseux algebra K[S]K[S] is an FFD if and only if SS is an FFM, when KK is a finitely generated field of characteristic 00. This would provide a large class of one-dimensional monoid algebras with finite factorization property. We also prove that every generalized cyclotomic polynomial has the finite factorization property in K[S]K[S] where SS is a reduced FFM and KK is an arbitrary field of characteristic 00.
