In mathematics, a ring class field is the abelian extension of an algebraic number field K associated by class field theory to the ring class group of some order O of the ring of integers of K.[1]

Properties

edit

Let K be an algebraic number field.

Let L be the ring class field for the order Z[n] in the number field K = Q(n).
