SUMMARY:COW: The integral Hodge conjecture for 3-folds - Burt Totaro (Camb
 ridge)
DTSTART:20131114T140000Z

UID:TALK48410@talks.cam.ac.uk
CONTACT:Dr. J Ross
DESCRIPTION:Hodge originally conjectured that every Hodge class\nin the in
 tegral cohomology of a smooth complex projective\nvariety is algebraic\, m
 eaning the class of a Z-linear\ncombination of subvarieties. This is false
  in general.\nWe discuss recent positive and negative results\non the inte
 gral Hodge conjecture for 3-folds. \n\nThis talk is part of the Cambridge-
 Oxford-Warwick (COW) seminar.
