叶理自同构群的多项式界

Polynomial bounds for automorphisms groups of foliations

Maurício Corrêa, Alan Muniz

摘要:

设$(X, \mathcal{F})$是一个叶状曲面,$G$是$X$的有限自同构群,它保持$\mathcal{F}$ .我们调查不变的轨迹$G$,并获得其阶的上界多项式依赖于陈数的$X$和$\mathcal{F}$。作为结果,我们估计的阶的自同构群的一些叶理在温和的限制。利用Jouanolou叶理的自同构群得到了射影平面上叶理的一个最优界。

英文摘要:

Let $(X, \mathcal{F})$ be a foliated surface and $G$ a finite group of automorphisms of $X$ that preserves $\mathcal{F}$. We investigate invariant loci for $G$ and obtain upper bounds for its order that depends polynomially on the Chern numbers of $X$ and $\mathcal{F}$. As a consequence, we estimate the order of the automorphism group of some foliations under mild restrictions. We obtain an optimal bound for foliations on the projective plane which is attained by the automorphism groups of the Jouanolou's foliations.
