A remark on the product by the hyperplane class in the Chow ring of some complete intersections

René Mboro

By classical calculation, for a smooth hypersurface $Y \subset P_{C}^{n + 1}$ , the product by the hyperplane class is zero on homologically trivial rational cycles i.e…

Remarks on the geometry of the variety of planes of a cubic fivefold

René Mboro

This note presents some properties of the variety of planes $F_{2} (X) \subset G (3, 7)$ of a cubic $5$ -fold $X \subset P^{6}$ . A cotangent bundle exact sequence is first derived fr…

Remarks on the $CH_{2}$ of cubic hypersurfaces

René Mboro

This paper presents two approaches to reducing problems on $2$ -cycles on a smooth cubic hypersurface $X$ over an algebraically closed field of characteristic $\neq = 2$ , to problems…

On the universal $CH_{0}$ group of cubic threefolds in positive characteristic

René Mboro

We adapt for algebraically closed fields $k$ of characteristic greater than $2$ two results of Voisin, on the decomposition of the diagonal of a smooth cubic hypersurface $X$ of di…
