Gluing determinantal Cremona maps
Rémi Bignalet-Cazalet
We study determinantal Cremona maps, i.e. birational maps whose base ideal is the maximal minors ideal of a given matrix , via the resolution of the polynomials systems defined…
Plane polar Cremona maps of arbitrarily large degree in positive characteristic
Remi Bignalet-Cazalet
A result of I.V.Dolgachev states that the complex homaloidal polynomials in three variables, i.e. the complex homogeneous polynomials whose polar map is birational, are of degree a…
Torsion of a finite base locus
Rémi Bignalet-Cazalet
We interpret geometrically the torsion of the symmetric algebra of the ideal sheaf of a zero-dimensional scheme Z defined by equations in an -dimensional variety. This lea…
Resolution of the symmetric algebra of a finite base locus
Rémi Bignalet-Cazalet
We provide a locally free resolution of the projectivized symmetric algebra of the ideal sheaf of a zero-dimensional scheme defined by n + 1 equations in an n-dimensional variety.…
