Explore recent developments in the three-dimensional minimal model program in this 42-minute lecture by Yuri Prokhorov. Gain insights into the basic operations, steps, and outcomes of the MMP. Delve into terminal 3-fold singularities, general elephant theorems, and the classification of extremal curve germs. Examine divisorial contractions, Q-del Pezzo fibrations, and the effective boundedness of Q-Fano 3-folds. Access accompanying slides for visual support and deeper understanding of this advanced mathematical topic.
