| Post subject: | Polynomials over Q(t) |
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? |
