Topic review - Polynomials over Q(t)

  Post subject:  Polynomials over Q(t)  Reply with quote
I am trying to do some computations using polynomials over Q(t). But already the following hangs my machine:

ring R = (0,t), (w,x,y,z), dp;
poly f = w^3 + x^3 + y^3 + z^3 + t*((w+x)*(w+2*y)*(w+3*z) + 3*x*y*(w+x+z));
ideal jac = jacob(f);
print(lift(jac, x^4));

By contrast, Magma does this with no trouble. Is this a known issue?
