Hi,

Is there an absolute irreducibility check in giac/XCas? In maple we have AIrreduc to check absolute irreducibility. For instance I can do:

Code : Tout sélectionner

evala(AIrreduc(x^2+y^2+z^2)); #returns true
evala(AIrreduc(x^2+y^2)); #returns false

There is no builtin command, but if you open Help>Examples>poly>afactor.xws, there is a program that does absolute factorization, absolute irreductibility can be viewed as a particular case.
