Plane Cremona maps preserving a Euclidean volume form

Year: 2026

Type: preprint

Abstract: We give a presentation by generators and relations of the group of birational transformations of the plane preserving a differential form with poles along a triple line. This group strictly contains the automorphism group of the affine plane.
