Dear all, given a multivariate monomial defined with:
poly := MPOLY([x,y], Integer) p : poly := 3*x*y one can obtain the factors of the monomial with factors(p). However, given a multivariate monomial with noncommutative variables defined with: ops := OVAR[A,B] ncomm := XDPOLY(ops, Integer) q : ncomm := 3*B::ops*A::ops factors(q) fails. I did some research and learned that: - factors ultimately retrieves an entry from a record corresponding to the representation of an object in the Factored domain - multivariate polynomials are domains in the PolynomialCategory, which in its definition contains the line import from Factored(%) - in the noncommutative case the corresponding category is XPolynomialsCat, which is more modest than PolynomialCategory, i.e. it is missing a lot of stuff It is not clear to me whether the above import statement is the reason why one can obtain the factors in the commutative case. What I would like to know is, how should I modify XPolynomialsCat in order to have factors available. Thanks in advance.
