Aim of the School.
The School is mainly aimed to Phd students and young researchers in Algebraic Geometry, introducing the participants to research, beginning from a basic level with a view towards the applications and to the most recent results.
I. Cheltsov. Dimension 2. G-rigid del Pezzo surfaces. G-rigid conic bundles. Simple subgroups in the plane Cremona group. p-groups in plane Cremona group. G-Sarkisov links between G-Fano varieties. Three-dimensional examples. The case of algebraically non-closed field. G-rigid Fano threefolds. Cases when G is a simple group of order either 168 and 360. Essential dimension of finite groups and Cremona groups. Duncan's theorems. Kollar-Szabo theorem. Icosahedron subgroups in space Cremona groups.
Y. Prokhorov. Regularization of birational automorphisms, G-Minimal Model Program, G-Mori fiber spaces, examples. G-Fano varieties. Riemann–Roch theorem for non-Gorenstein threefolds. Bogomolov-Miyaoka-Yau inequality. Applications. Simple subgroups of space Cremona group (answer to a question of Serre). Big finite subgroups of the space Cremona group: p-groups and symmetric group of order 720. Cohomological approach to the study of finite subgroups of Cremona groups.
