This is an online learning seminar series on Birkar's multiple work on Fano varieties, singularities, and related topics. The focus will be on main results, key ideas, applications, and open problems. The aim is to help researchers and students learn about this very exciting area of algebraic geometry and to stimulate further work. The seminar will be held online via Zoom
Abstract Generalised pairs are a natural structure in birational geometry that first appeared in Kodaira’s canonical bundle formula for elliptic fibrations. They were formally introduced by Birkar and Zhang in 2014 as part of their study of effective Iitaka fibrations and have since become a central topic in modern-day birational geometry. In particular, they have been essential in Birkar proo...
