WebTheorem 20.1. Every nite abelian extension of Q lies in a cyclotomic eld Q( m). There is also a local version. Theorem 20.2. Every nite abelian extension of Q p lies in a cyclotomic eld Q p( m). Our rst step is to show that it su ces to prove the local version. Proposition 20.3. The local Kronecker-Weber theorem implies the global Kronecker ... WebKronecker sum A A (= A I + I A) into a direct sum of irreducible matrices, when A is a 3 3 matrix. As a consequence we identify K(A A) as the direct sum of several full matrix algebras as predicted by Artin{Wedderburn theorem, where K(T) is the unital algebra generated by T and T . 1. Introduction
