Hi, I'm trying to compute something using multivariate polynomials, and am struggling to understand the relation between polynomials of type <type 'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'> and of type <class 'sage.rings.polynomial.multi_polynomial_element.MPolynomial_polydict'>.
How does one create one or the other? And, mainly: how can one convert from one to the other? What happened to me is that I unwillingly created some polynomial of one type and some of the other and than methods like P.coefficient(Q.monomials()[0]) object that they got argument of wrong type. (Here P and Q are polynomials of the respective types.) I'm sorry for not giving specific lines how to reproduce this, but -- in this case this is the point ... I got my polynomials P and Q over the course of several days and don't quite understand what happened. Thanks!
