Abstract

We describe a new algorithm for the localization of an algebraic hypersurfaceV inR n or Cn. This algorithm computes a decreasing sequence of closed sets whose intersection isV. In the particular case of an hypersurface without any point at infinity, the notion of the asymptotic cone is used to determine a compact set containing this hypersurface. We give also a numerical version of this algorithm.
