Determinantal maps and their palindromic projective degrees

Rémi Bignalet-CazaletParis

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.
