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.
