Components of maximal dimension in the Noether-Lefschetz locus for Beilinson-Hodge cycles on open surfaces
M. Asakura, S. Saito
The main subject of study in this paper is the Noether-Lefschetz locus for Beilinson-Hodge cycles on the complement of the union of hyperplane sections in a surface in .…

Estimate of dimension of Noether-Lefschetz locus for Beilinson-Hodge cycles on open complete intersections
M. Asakura, S. Saito
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…
