Hello all:
Is there a Singular function (or any algorithm whatsoever) that, given a finite set of algebraically dependent multivariate polynomials f_1,...,f_k (over the rationals, say), computes an irreducible annihilating polynomial for that set, that is, a nonzero irreducible polynomial P (with rational coefficients) such that P(f_1,...,f_k) = 0? I searched the Singular documentation on this topic but didn't find anything.
Cheers, Alex

Yes, there are 3 procedures in algebra.lib
algebra_containment inSubring algDependent
testing algebraic dependence by different algoruthms.
