AlgebraicNumberNorm

AlgebraicNumberNorm[a]
gives the norm of the algebraic number a.
  • The norm of a is defined to be the product of the roots of its minimal polynomial.
Integers and rational numbers:
Radical expressions:
Root and AlgebraicNumber objects:
AlgebraicNumberNorm automatically threads over lists:
Norm of over :
is irreducible in :
Since AlgebraicNumberNorm is multiplicative, having a prime norm implies the original number is prime:
AlgebraicNumberNorm is multiplicative:
Units in a number field have norm +/-1:
