Abstract: Witten's conjecture of 1991 evaluates certain intersection numbers on the moduli spaces of curves using the Korteweg-de Vries equation. Several mathematical approaches to this statement were found, the first one due to Kontsevich. Recently, rather dramatic shortcuts to the goal were discovered. I will explain one of them, following the work of Lando and Kazarian. My aim is to make the lectures self-contained and accessible to general mathematical audience. 


Andrei Okounkov was awarded the Fields Medal in 2006 "for his contributions bridging probability, representation theory and algebraic geometry".
