Equivalence of K3 surfaces from Verra threefolds

Algebraic Geometry 2020-12-23 v2

Abstract

We study (2,2) divisors in P2×P2P^2 \times P^2 giving rise to pairs of non-isomorphic, derived equivalent and L-equivalent K3 surfaces of degree 2. In particular, we confirm the existence of such fourfolds as predicted by Kuznetsov and Shinder in \cite{KS}.
