Coniveau 2 complete intersections and effective cones

abstract: We give a geometric interpretation of the numerical characterization of coniveau 2 complete intersections. This involves the geometry of certain subvarieties of the corresponding Fano variety of lines: they are ''very moving''. We show that the generalized Gorthendieck-Hodge conjecture would follow from knowing that the classes of these subvarieties are big.
