In algebraic number theory, the Hilbert class field E of a number field K is the maximal abelian unramified extension of K. Its degree over K equals the class number of K and the Galois group of E over K is canonically isomorphic to the ideal class group of K using Frobenius elements for prime ideals in K. In this context, the Hilbert class field of K is not just unramified at the finite places (the classical i… Web4. The answer is no. Take K = Q ( − 5 4). Then C l ( K) is cyclic of order 4 , and its Hilbert class field is given by H = L ( i, 1 + 2 i). This field is the compositum H = K F of the two dihedral extensions K and F = Q ( i, 5, 1 + 2 i), hence is normal over the rationals. Edit (2015).

WebIts Hilbert class field can be formed by adjoining a root of x3- x - 1, which has discriminant -23. To see why ramification at the archimedean primes must be taken into account, consider the realquadratic fieldKobtained by adjoining the square root of 3 to Q.
