“…[43,Section 4.3.5.2]. Conjecture 4.1 has been proven in some scattered special cases [41], [24], [25], [26], [27], [6], [29], [7], [28], but is still wide open for a general K3 surface.…”
We consider Calabi-Yau n-folds X 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 X generated by divisors, Chern classes and intersections of subvarieties of positive codimension injects into cohomology. We also prove Voisin's conjecture for X, and Voevodsky's smash-nilpotence conjecture for odd-dimensional X.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
