ruled surfaces上秩2向量丛的非常满的判定

Criteria for very ampleness of rank two vector bundles over ruled surfaces

Alberto Alzati, GianMario Besana

摘要:

给出了有理曲线和椭圆曲线上光滑直纹曲面上秩为2的向量丛的很满准则。然后利用这些准则解决了某些特殊的低次三重解的存在性问题。

英文摘要:

Very ampleness criteria for rank 2 vector bundles over smooth, ruled surfaces over rational and elliptic curves are given. The criteria are then used to settle open existence questions for some special threefolds of low degree.
