for instance nef cycles that fail to be pseudoeffective: this answers a question raised in 1964 by Grothendieck in correspondence with Mumford. 1 Classical topics in projective geometry. E-mail: totaro@math.ucla.edu. Claire Voisin, (Jussieu/IAS) Title: Coniveau and algebraic cycles on very general complete intersections Abstract: There are two notions of coniveau (Hodge and geometric) for smooth projective varieties, which should be equivalent according to Grothendieck-Hodge conjecture. Alexander Grothendieck, 'Hodge's general conjecture is false for trivial reasons', Topology, 8 (3), 299 - 303 (1969). 4 Algebraic geometry: classical approach.
