SUMMARY:Seminar Algebra and Geometry: Marc Chardin (Institut Mathématique 
 de Jussieu\, Paris)
DESCRIPTION:In this lecture\, I will present a way of computing the image o
 f a   rational map using a free resolution of the symmetric algebra. In t
 his  setting\, the  method was initiated by Jean-Pierre Jouanolou\, and f
 urther  developed by him\, by Laurent  Busé and by myself. The origin of
  this  method is the work of people in Geometric  Modeling\, motivated by
  a  simple question: how to represent the  intersection of two surfaces  
 parametrized by rational functions?  \\r\\nTheir approach was first put on
  firm mathematical bases by David Cox  and several collaborators. The key
   point in this approach is to control  the torsion in the symmetric alge
 bra. This is performed using a  construction of Herzog\, Simis and Vasconc
 elos\, that gives information on  the equations of Rees algebras.
