How to set variable order (not term order) in polynomial ring?
I need to create a PolynomialRing in sage, with an unknown number of variables x0,...,xn. For this I use the following code:
R = PolynomialRing(QQ, 'x', 3, order='degrevlex');
R.inject_variables(verbose=False)
In this case, n = 2. However, I also want x2 to be considered greater than x1.
Instead, I get the following:
sage: x1 < x2;
False
How can I set the variable order of my ring to have x0 < x1 < ... < xn?
