Foliated Minimal Models and Flops

Paolo Cascini, Roktim Mascharak, Calum Spicer

We study minimal models and flops for foliations. We show that if is a rank one foliation with canonical singularities on a normal projective -factorial var…

Relative semi-ampleness in positive characteristic

Paolo Cascini, Hiromu Tanaka

Given an invertible sheaf on a fibre space between projective varieties of positive characteristic, we show that fibrewise semi-ampleness implies relative semi-ampleness. The same…

Birational boundedness of stable families

Paolo Cascini, Jihao Liu, Calum Spicer +1

We prove that normal projective stable families of maximal variation, of fixed dimension, and with bounded adjoint volume are birationally bounded. This is a consequence of a subst…

A Matsushima theorem for K-polystable polarised smooth Fano threefolds

Hamid Abban, Paolo Cascini, Ivan Cheltsov

We prove that if is a smooth Fano threefold and is an ample -divisor such that is K-polystable, then the automorphism group is r…

Recent progress on the Minimal Model Program for foliations

Paolo Cascini, Calum Spicer

We survey recent progress on the birational geometry of foliations on complex varieties. We focus on the MMP viewpoint: singularities, adjunction and applications to the MMP for fo…

On base point freeness for rank one foliations

Paolo Cascini, Calum Spicer

We prove the base point free theorem for log canonical foliated pairs of rank one on a Q-factorial projective klt threefold. Moreover, we show abundance in the case of numerically…
