Abelian Fields, the Kronecker-Weber theorem (Theorem 6.18) every such extension is contained in a suitable cyclotomic field .. = ℚ(ζ.). The least integer . with the property .⊂.. is called the . of ., and is denoted by .(.).S The main properties of the conductor are listed in the following proposition:

However, for numeri­ cal computations, necessary for applications of algebraic numbers to other areas of number theory, the old approach seems more suitable, although i
