Derived equivalence of Ito–Miura–Okawa–Ueda Calabi–Yau 3-folds

Abstract

We prove derived equivalence of Calabi–Yau threefolds constructed by Ito–Miura–Okawa–Ueda as an example of non-birational Calabi–Yau varieties whose difference in the Grothendieck ring of varieties is annihilated by the affine line.
