论文摘要
我们研究了具有给定的一组自动形态的复杂的投射平面曲线。令$ g $为$ pgl(3,\ mathbb {c})$的简单原始子组,它是同构对$ a_ {6} $,$ a_ {5} $或$ psl(2,\ mathbb {f} _ {7})$。对于$ d $ $ d $不变的$ g $,我们获得了$ d $的必要条件。我们还研究了整体曲线上的类似问题。
We study complex projective plane curves with a given group of automorphisms. Let $G$ be a simple primitive subgroup of $PGL(3, \mathbb{C})$, which is isomorphic to $A_{6}$, $A_{5}$ or $PSL(2, \mathbb{F}_{7})$. We obtain a necessary and sufficient condition on $d$ for the existence of a nonsingular projective plane curve of degree $d$ invariant under $G$. We also study an analogous problem on integral curves.
