This is an introduction course on the minimal model program. For surfaces, we will cover the cone theorem, the non-vanishing for pairs and generalized polarized pairs, the abundance theorem, Sarkisov program, Zariski decomposition, the ACC for MLD, the ACC for a-LCT, the theory of complements, Birkar-Borisov-Alexeev-Borisov, boundedness of LCT of linear systems, etc.

 

1.The cone theorem, Sarkisov program (Chapter 1-2, Introduction to the Mori Program)

2.The non-vanishing for pairs and the abundance theorem (Chapter 11, Flips and abundance for algebraic threefolds; ON NUMERICAL NONVANISHING FOR GENERALIZED LOG CANONICAL PAIRS, https://arxiv.org/pdf/1808.06361.pdf)

3. the ACC for MLD, the ACC for a-LCT (Valery Alexeev, Two two--dimensional terminations, Duke Math. J., 69(3), 1993: 527—545; V.V. Shokurov, A.c.c. in codimension 2, 1991 (preprint).)

4. the theory of complements, Birkar-Borisov-Alexeev-Borisov, boundedness of LCT of linear systems (Lectures on complements on log surfaces, etc.)

Grading: No homework. The final assessment for this class will be a 10-20 pages paper on a topic related to the course material.
