Abstract

By classical calculation, for a smooth hypersurface YPCn+1Y\subset \mathbb P^{n+1}_{\mathbb C}, the product by the hyperplane class is zero on homologically trivial rational cycles i.e. HY:CHi(Y)hom,QCHi1(Y)hom,QH_{|Y}\cdot :{\rm CH}_i(Y)_{hom,\mathbb Q}\rightarrow {\rm CH}_{i-1}(Y)_{hom,\mathbb Q} is 00 for any ii. This note extends that result to some complete intersections.
