On the Chow ring of some special Calabi-Yau varieties

Algebraic Geometry 2021-05-11 v1

Abstract

We consider Calabi-Yau nn-folds XX arising from certain hyperplane arrangements. Using Fu-Vial's theory of distinguished cycles for varieties with motive of abelian type, we show that the subring of the Chow ring of XX generated by divisors, Chern classes and intersections of subvarieties of positive codimension injects into cohomology. We also prove Voisin's conjecture for XX, and Voevodsky's smash-nilpotence conjecture for odd-dimensional XX.
