$2$ -幂零co-Higgs结构

$2$-nilpotent co-Higgs structures

Edoardo Ballico, Sukmoon Huh

摘要:

co-Higgs层是一对无挠相干层$\mathcal{E}$和$\mathcal{E}nd(\mathcal{E})\otimes T_X$的整体瓣,其中$T_X$是切丛。利用Hartshorne-Serre对应,我们构造了一些有理曲面的秩为2的$2$ -幂零co-Higgs层和$\mathbb{P}^3$的秩为3的$2$ -幂零co-Higgs层.然后我们研究了非存在性,特别是在射影空间上。

英文摘要:

A co-Higgs sheaf is a pair of a torsion-free coherent sheaf $\mathcal{E}$ and a global section of $\mathcal{E}nd(\mathcal{E})\otimes T_X$ with $T_X$ the tangent bundle. We construct $2$-nilpotent co-Higgs sheaves of rank two for some rational surfaces and of rank three for $\mathbb{P}^3$, using the Hartshorne-Serre correspondence. Then we investigate the non-existence, specially over projective spaces.
