J + 2G = 5 where J = 1 & G = 2
K
Let K be a number field and n=[K:Q]=r1+2r2 where r1 is the number of real embeddings K↪C , and r2 the number of pairs of complex embeddings K↪C . Then
OK*≅μ(K)?-Zr1+r2−1,
where μ(K) is the set of roots of unity in K .
Put another way, this means that there are r=r1+r2−1 "fundamental units" ɛ1,
,ɛr such that any unit u∈OK* can be written uniquely as
u=ζɛ1n1
ɛrnr
for some ζ∈μ(K) .
