Title:Derived equivalent rational threefolds
Seminar:Algebra and Number Theory Seminar
Speaker:John Lesieutre, MIT
Abstract:
I will describe the construction of an infinite set of smooth projective threefolds that have equivalent derived categories but are not isomorphic, contrary to a conjecture of Kawamata. The example is quite elementary: the varieties arise as blow-ups of CP^3 at various configurations of 8 points, related by sequences of Cremona transformations. As time permits, I will discuss how related constructions give rise to some other counterexamples in birational geometry.
