Equivalence of K3 surfaces from Verra threefolds

Abstract

We study (2,2) divisors in $P^2\times P^2$ 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}.
