Normal split divisors in rational homogeneous spaces
Enrica Floris, Andreas Höring
We show that a divisor in a rational homogenous variety with split normal sequence is the preimage of a hyperplane section in either the projective space or a quadric.
A description of the sarkisov program of horospherical varieties via moment polytopes
Enrica Floris, Boris Pasquier
Let X and Y be horospherical Mori fibre spaces which are birational equivariantly with respect to the group action. Then, there is a horospherical Sarkisov program from X/S to Y /T…
Normal split submanifolds of rational homogeneous spaces
Enrica Floris, Andreas Höring
Let be a submanifold of a rational homogeneous space such that the normal sequence splits. We prove that is also rational homogeneous.
On the restriction of the moduli part to a reduced divisor
Enrica Floris
Let be a fibration such that is torsion along the fibres of . Assume that has dimension 2, or that has dimension 3 and the fibres have d…
Connected algebraic groups acting on Fano fibrations over
Jérémy Blanc, Enrica Floris
Let be a Mori fibre space with general fibre of Picard rank at least two. We prove that there is a proper closed subset , invariant by the connected…
Divisorial contractions to codimension three orbits
Samuel Boissière, Enrica Floris
Let be a connected algebraic group. We study -equivariant extremal contractions whose centre is a codimension three -simply connected orbit. In the spirit of an important…
