AFactor - inert absolute factorization

Calling Sequence

AFactor(p)

Parameters

p

-

multivariate polynomial

Description

• 

The AFactor function is a placeholder for representing an absolute factorization of the polynomial p, that is a factorization over an algebraic closure of its coefficient field. It is used in conjunction with evala.

• 

The call evala(AFactor(p)) computes the factorization of the polynomial p over the field of complex numbers. The polynomial p must have algebraic number coefficients.

• 

In the case of a univariate polynomial, the absolute factorization is just the decomposition into linear factors.
