Determinantal maps and their palindromic projective degrees

Rémi Bignalet-Cazalet
Paris


the projective degrees of a rational map between projective 
spaces are the degrees of the pre-images of general linear spaces of 
increasing dimension. In this talk, after explaining how to compute 
these projective degrees in concrete situations, I will present the 
construction of determinantal maps, i.e. rational maps whose 
components are the maximal minors of a matrix, having palindromic 
projective degrees. In particular, this construction gives the 
description of Cremona maps, i.e. birational map between projective 
spaces, with specific projective degrees.
