WebMay 1, 1970 · Hilbert's theorem 94 [3] concerns itself with a cyclic unramified extension, K, of an algebraic number field, F. In such an extension, it is shown that the subgroup of the ideal class group of F which becomes principal in K has order divisible by the degree [K: F]. It is not, in general, known which subgroup becomes principal.
