projective varieties上的超越Liouville不等式

Transcendental Liouville inequalities on projective varieties

Carlo Gasbarri

摘要:

设$p$是数域上射影簇$X$的代数点. Liouville不等式告诉我们,$X$上厄米线丛的非零整整体瓣在$p$上的范数要么为零,要么相对于截面本身的$\sup$范数不能太小.我们研究的不平等类似刘维的子变量和超越点的射影簇定义在数域。我们证明了几乎所有的超越点都证明了一个好的Liouville型不等式。我们还涉及到我们的方法(前)猜想Chudnowsky,并给出两个应用程序的增长数量的有理点的有界高度的图像上的解析映射从一个磁盘的投影品种。

英文摘要:

Let $p$ be an algebraic point of a projective variety $X$ defined over a number field. Liouville inequality tells us that the norm at $p$ of a non vanishing integral global section of an hermitian line bundle over $X$ is either zero or it cannot be too small with respect to the $\sup$ norm of the section itself. We study inequalities similar to Liouville's for subvarietes and for transcendental points of a projective variety defined over a number field. We prove that almost all transcendental points verify a good inequality of Liouville type. We also relate our methods to a (former) conjecture by Chudnowsky and give two applications to the growth of the number of rational points of bounded height on the image of an analytic map from a disk to a projective variety.
