Estimate of dimension of Noether-Lefschetz locus for Beilinson-Hodge cycles on open complete intersections
arXiv:math/0304088
Abstract
We study an analogue of the Noether-Lefschetz theorem in the context of Beilinson's Hodge conjecture. We estimate the dimension of the Noether-Lefschetz locus by the infinitesimal methods in Hodge theory.
