NumberFieldNormRepresentatives

NumberFieldNormRepresentatives[a,m]

gives a list of representatives of classes of algebraic integers of norm +/-m in the field generated by the algebraic number a.

Details

  • Algebraic integers are considered to be in the same class if their quotient is a unit in the field .
  • All elements of the number field with norm +/-m can be obtained from the representatives by multiplication by units in the field.
