Thank you for your response. I will take your remarks into account in the future.
I will therefore answer your questions. In fact, I have polynomials with two categories of variables:
Category 1: the variables X1, X2,..., XN,
and a second category: the variables U1, U2,..., UK.
These polynomials are on the field of reals.
I then consider the polynomials of the variables of category 1 having polynomial coefficients with the variables of the second category.
At the end of my calculations, I obtain sets or lists of such polynomials, and in these sets or lists there are redundancies from the point of view of the polynomials in the variables of category 1. More precisely, I obtain polynomials that differ only by one factor belonging to the polynomials in the variables of category 2. I would like to keep only the common polynomial part in the variables of category 1.
I would then like to keep in my list or set only the polynomial:
Is my precision appropriate?
Thank you in advance.
