我们研究了平面曲线 $C$ 定义方程的雅可比理想的合子与沿 $C$ 的对数向量场束的稳定性、除数 $C$ 的自由度以及 $C$ 的 Torelli 性质(在 Dolgachev-Kapranov 意义上)之间的关系。 我们特别表明,在这个意义上,具有少量节点和尖点的曲线是托雷利曲线。
We investigate the relations between the syzygies of the Jacobian ideal of the defining equation for a plane curve $C$ and the stability of the sheaf of logarithmic vector fields along $C$, the freeness of the divisor $C$ and the Torelli properties of $C$ (in the sense of Dolgachev-Kapranov). We show in particular that curves with a small number of nodes and cusps are Torelli in this sense.
