A Griffiths' theorem for varieties with isolated singularities
The main statement of this article is a generalization of a theorem of Griffiths which asserts that on certain smooth even dimensional projective varieties homological and algebraic equivalence do not coincide for higher codimension cycles. Here the varieties are allowed to have at most isolated singularities. The proof is obtained via the analysis of a particular pencil of hypersurfaces and comparison of Abel-Jacobi maps.
