Abstract or Additional Information
One of the Fields Medals this year went to Caucher Birkar for his birational geometry work, that included in particular a proof of so-called Borisov-Alexeev-Borisov conjecture. This conjecture was proposed independently by me and Valery Alexeev around 1993. I will give a short introduction to the subject, to state the BAB conjecture (now Birkar's Theorem) and discuss some related results and open questions.
