From flips to functors

, 2020
A healthy body of evidence says that birational geometry and derived categories are intimately bound. Even so, many basic questions are still open. One of the most central questions is the conjecture of Bondal and Orlov (later extended by Kawamata) that ...

Explicit Examples of Rational and Calabi-Yau Threefolds with Primitive Automorphisms of Positive Entropy

, 2015
We present the first explicit examples of a rational threefold and a Calabi-Yau threefold, admitting biregular automorphisms of positive entropy not preserving any dominant rational maps to lower positive dimensional varieties.
