Let L be a Galois extension of the number field K . Set n = n K = deg K/ℚ , n L = deg L /ℚ and n L / K = deg L/K . Let I = I L/K denote the group of fractional ideals of K whose prime decomposition contains no prime ideals that ramify in L , and let P = {(α)Σ I : αΣ K *, α>0}. Following Hecke [9}, let (λ 1 , λ 2 , …, λ n − 1 ) be a basis for the torsion-free characters on P that satisfy λ i (α) = 1 (1≤ i ≤ n − 1) for all units α>0 in , the ring of integers of K . Fixing an extension of each λ i to a character on I , then λ i ,( α ) (1 ≤ i ≤ n − 1) are defined for all ideals α of K that do not ramify in L . So, for such ideals, we can define . Then the small region of K referred to above is for 0 l with the notation that, for any α ∈ ℝ, we set β. where β is the unique real satisyfing .
