空间曲线法丛的稳定性

Stability of Normal Bundles of Space Curves

Izzet Coskun, Eric Larson, Isabel Vogt

摘要:

本文证明了一般Brill-Noether空间曲线的法丛是稳定的当且仅当$g \geq 2$.当$g\leq1$和基域的特征为零时,法丛是严格半稳定的。我们发现,这失败的特点$2$的所有有理曲线的偶数度。

英文摘要:

In this paper, we prove that the normal bundle of a general Brill-Noether space curve of degree $d$ and genus $g \geq 2$ is stable if and only if $(d,g) \not\in \{ (5,2), (6,4) \}$. When $g\leq1$ and the characteristic of the ground field is zero, it is classical that the normal bundle is strictly semistable. We show that this fails in characteristic $2$ for all rational curves of even degree.
