Title: Symmetric square of a cubic hypersurface and Fano variety of lines
Date: Nov 14, 2013, 11:00-13:00
Jointly with Evgeny Shinder we prove a universal relation between classes of a cubic hypersurface, its symmetric square and variety of lines on it in the Grothendieck ring of varieties. As a corollary, one can find various invariants of variety of lines, in particular find how many lines are there on a cubic surfaces over various fields.
