- | I will tell about the problems in birational geometry and tools for solving them. | + | * 29/03/2014 Sergey Galkin: Grothendieck' |
- | I will introduce various flavours of rationality: | + | * 5/ |
- | and rationally connected varieties, and describe the subtle differences between them. | + | |
- | Also I'll tell known theorems, examples, conjectures and counterexamples, | + | |
- | regarding rationality of cubic hypersurfaces and other related varieties. | + | |

- | (ring of generalized Euler characteristic or so-called " | + | |
- | and show how it could be used for solving rationality problems, using theorem of Larsen and Lunts. | + | |
- | I will demonstrate a beautiful identity in this ring, that relates symmetric square of cubic | + | |
- | hypersurface with its Fano variety of lines. We will use this identity to show, | + | |
- | that if class of an affine line is not a zero divisor in the Grothendieck ring of complex varieties, | + | |
- | then variety of lines on a rational cubic fourfold is birational to symmetric square of a K3 surface, | + | |
- | in particular, generic cubic fourfold is irrational. This is a joint work with Evgeny Shinder. | + | |
