JugendtraumKronecker proved that all the Galois extensions of the RationalsQ with Abelian Galois groups are Subfields of cyclotomicfields , where is the group of th Roots of Unity. He then sought to find asimilar function whose division values would generate the Abelian extensions of an arbitrary Number Field. Hediscovered that the j-Function works for Imaginary quadratic number fields , but thecompletion of this problem, known as Kronecker's Jugendtraum (``dream of youth''), for other fields remains one of the greatunsolved problems in Number Theory.
