Hilbert's 18th problem

WebKronecker's Jugendtraum or Hilbert's twelfth problem, of the 23 mathematical Hilbert problems, is the extension of the Kronecker–Weber theorem on abelian extensions of the rational numbers, to any base number field.That is, it asks for analogues of the roots of unity, as complex numbers that are particular values of the exponential function; the …
