具有大量自同构群的有理曲面

Rational surfaces with a large group of automorphisms

Serge Cantat, Igor Dolgachev

摘要:

我们分类的有理曲面的自同构群的图像的组的线性变换的Picard组是最大的可能。这回答了Arthur Coble在1928年提出的一个问题,并且可以用无限Coxeter群在射影平面模射影等价的有序点集上的双有理作用的周期轨道来重新表述。我们还概述了大的自同构群的非理性曲面的分类。

英文摘要:

We classify rational surfaces for which the image of the automorphisms group in the group of linear transformations of the Picard group is the largest possible. This answers a question raised by Arthur Coble in 1928, and can be rephrased in terms of periodic orbits of a birational action of an infinite Coxeter group on ordered point sets in the projective plane modulo projective equivalence. We also outline the classification of non-rational surfaces with large automorphism groups.
