定理如果存在一个拓扑同构v:G 1 G 2,则对应域z:Q,I Q 2的一个唯一同构,使得对于每个g,e G 1,U(g J = rgl 1).在[6]中证明了代数数域的一个类似定理,尽管那里假设Q1 = Q2。素因子的一一对应本质上是由于Neukirch [3],[4]。第1节和第2节中的大多数参数在数域的情况下也是有效的。
THEOREM. If there exists a topological isomorphism v: G1 G2, there corresponds a unique isomorphism of fields z: Q, I Q2 such that U(gJ = rgl 1 for every g, e G1. An analogous theorem for algebraic number fields was proved in [6], though Q1 = Q2 was assumed there. One-to-one correspondence of prime divisors is essentially due to Neukirch [3], [4]. Most of the arguments in Sections 1 and 2 are also valid in the number field case.
