Description: |
To each hypersurface X in the projective n-space, we associate a rational map Pn--->Pn, called its polar map, given simply by the partial derivatives of the polynomial that defines X. This is a classical theme in projective geometry; the central problem is the classification of homaloidal hypersurfaces, that is, those with a birational polar map. In the last two decades there has been a significant progress on the subject, with new results coming from many different areas.
In this talk we present our approach, which is done via two different perspectives: holomorphic foliations and characteristic classes. We also give some applications and a brief report on ways to deal with more general situations.
