Intersection-product conjecture for odd-dimensional or Calabi–Yau hypersurfaces

Let XPn+1(C)X\subset\mathbb{P}^{n+1}(\mathbb{C}) be a smooth hypersurface. Assume that either the dimension nn is odd, or the degree of XX is n+2n+2, so that XX is Calabi–Yau. Intersection-product conjecture.

Ai(X)Aj(X)=Q[hi+j]for all i,j>0.A^i(X)\cdot A^{j}(X)=\mathbb{Q}[h^{i+j}]\quad\text{for all }i,j>0.

This conjecture combines Voisin's theorem for Calabi–Yau hypersurfaces with the preceding product conjecture. Its general validity is not established in the source.
