# On (2,3)-fourfolds

### John Christian Ottem (University of Oslo)

Fri Jul 10, 19:00-20:00 (4 months ago)

Abstract: I will explain how tropical degenerations and birational specialization techniques can be used in rationality problems. In particular, I will apply these techniques to study quartic fivefolds and complete intersections of a quadric and a cubic in $\mathbb{P}^6$. This is joint work with Johannes Nicaise.
