Webthe group ring of a ﬁnite group over an abelian number ﬁeld will be (Morita) equivalent to a cyclotomic algebra over a (possibly larger) abelian number ﬁeld F (see [15]). This meansthat the simple component FGe correspondingto χ ∈ Irr(G) can be expressed as a matrix ring over a cyclotomic algebra with center F(χ), Webrestores unique factorization for the rings in question. To begin a study of this theory, we start by investigating the elements of the rings of integers of cyclotomic elds, which Kummer called cyclotomic integers. De nition 1.1.
