Pollack introduces algebraic number theory to readers who are familiar with linear algebra, commutative ring theory, Galois theory, a little abelian groups theory, and elementary number theory up to and including the law of quadratic reciprocity.
Examples of such groups are: finite Abelian groups ([12], Theorem 4.
In fact for abelian groups (and much more general situations) we have by Schauenburg [Schau02] a Kunneth-type formula, and this decomposition does precisely explain the initially observed decomposition.
