自同构与典范理想

Automorphisms and the canonical ideal

Aristides Kontogeorgis, Alexios Terezakis, Ioannis Tsouknidas

摘要:

从规范嵌入和Petri定理的角度研究了曲线的自同构群。给出了自同构群是一般线性群的代数子群的一个判别准则。进一步将自同构群的作用推广到曲线$X$的标准环的最小自由分解的作用。

英文摘要:

The automorphism group of a curve is studied from the viewpoint of the canonical embedding and Petri's theorem. A criterion for identifying the automorphism group as an algebraic subgroup the general linear group is given. Furthermore the action of the automorphism group is extended to an action of the minimal free resolution of the canonical ring of the curve $X$.
