WebThe universal cyclotomic field is the infinite algebraic extension of Q generated by the roots of unity. It is also the maximal Abelian extension of Q in the sense that any Abelian Galois extension of Q is also a subfield of the universal cyclotomic field. Element # alias of UniversalCyclotomicFieldElement algebraic_closure() # Webthe class numbers of cyclotomic elds have only been determined for elds of small conductor, e.g. for prime conductors up to 67, due to the problem of nding the class number of its maximal real sub eld, a problem rst considered by Kummer. Our results have signi cantly improved the situation.
