On the closed image of a rational map and the implicitization problem
Laurent Buse, Jean-Pierre Jouanolou
In this paper, we investigate some topics around the closed image of a rational map given by some homogeneous elements of the same degree in a graded algebra…

Implicitization of surfaces in P^3 in the presence of base points
Laurent Buse, David Cox, Carlos D'Andrea
We show that the method of moving quadrics for implicitizing surfaces in P^3 applies in certain cases where base points are present. However, if the ideal defined by the parametriz…
