Evgeny Shinder
Evgeny Shinder (Sheffield) visited Laboratory of Algebraic Geometry in July 2013, November 2015, November 2016.
November 11th, 2016 he gave a talk "K3 L-zero divisors in the Grothendieck ring of varieties" at the weekly seminar of the Laboratory
Abstract: We discuss classes of non-isomorphic algebraic varieties X, Y such that [X] - [Y] is annihilated by a power of the affine line in the Grothendieck ring of varieties. Interesting examples include some derived equivalent Calabi-Yau threefolds (Borisov, Ito-Miura-Okawa-Ueda), and derived equivalent K3 surface pairs of degrees 8 and 2, 12 and 12, 16 and 4 (work in progress joint with A.Kuznetsov).
