WebHere, \very general" is usually taken to mean \in the complement of a countable union of Zariski closed subsets" in the moduli space of cubic fourfolds. At present, ... Some families of rational cubic fourfolds have been described by Fano [32], Tregub [56], [57], and Beauville{Donagi [8]. In particular, pfa an cubic fourfolds, de ned WebCubic fourfolds, i.e. nonsingular cubic hypersurface in projective five space, pose one of the most tantalizing challenges to the modern algebraic geometer: show that the very general cubic fourfold is not rational. Maybe somewhat embarrassingly, there is not a single known example of a cubic fourfold which is provably not rational!
