ON THE CHOW RING OF CERTAIN HYPERSURFACES IN A GRASSMANNIAN
ON THE CHOW RING OF CERTAIN HYPERSURFACES IN A GRASSMANNIAN
This note is about Plucker hyperplane sections X of the Grassmannian Gr(3, V 10). Inspired by the analogy with cubic fourfolds, we prove that the only non-trivial Chow group of X is generated by Grassmannians of type Gr(3, W 6) contained in X. We also prove that a certain subring …
