SUMMARY:Degree of the inverse of birational maps via the syzygies of the base loci
DESCRIPTION:Speaker: Hamid Hassanzadeh\, Federal University of Rio de Janeiro\n\nThis is a classical fact that if a plane Cremona map F:P^2-->P^2 is given by Polynomials of degree d then so does its inverse. A generalization of this fact for birational maps from P^n to P^n is due to Gabber who showed in 80's that the inverse map has degree at most d^{n-1}. However if one …
