可分解圈与Noether-Lefschetz轨迹

Decomposable cycles and Noether-Lefschetz loci

Kieran G. O'Grady

摘要:

证明了在射影三维空间中存在d次光滑曲面,使得可分解0-圈的有理等价类群的秩至少为(d-1)/3的整数部分.

英文摘要:

We prove that there exist smooth surfaces of degree d in projective 3-space such that the group of rational equivalence classes of decomposable 0-cycles has rank at least the integer part of (d-1)/3.
