Relations in the Grothendieck Ring and Homological Projective Duality
Abstract: It has recently been shown by Lev Borisov that the class of the affine line is a zero divisor in the Grothendieck ring of varieties. We place his construction in a more general context, and give a new proof using K3 surfaces rather than Calabi-Yau threefolds.
