Title: Existence of twisted Kahler-Einstein metrics in big classes
Speaker: Tamas Darvas (University of Maryland)

Time: 6:30 pm
Venue: Microsoft Teams (online)

We prove existence of twisted Kähler-Einstein metrics in big cohomology classes, using a divisorial stability condition. In particular, when -K_X is big, we obtain a uniform Yau-Tian-Donaldson existence theorem for Kähler-Einstein metrics. To achieve this, we build up from scratch the theory of Fujita-Odaka type delta invariants in the transcendental big setting, using pluripotential theory. This is joint work with Kewei Zhang.
