具有50阶自同构的K3曲面

K3 surfaces with an order 50 automorphism

JongHae Keum

摘要:

在不同于2和5的任何特征中,近藤给出了一个具有50阶纯非辛自同构的K3曲面的例子。该曲面被明确地表示为沿光滑六次曲线分支的双平面。本文证明了,在任何特征$p\neq 2, 5$中,具有50阶循环作用的K3曲面同构于Kondō的例子.

英文摘要:

In any characteristic different from 2 and 5, Kondō gave an example of a K3 surface with a purely non-symplectic automorphism of order 50. The surface was explicitly given as a double plane branched along a smooth sextic curve. In this note we show that, in any characteristic $p\neq 2, 5$, a K3 surface with a cyclic action of order 50 is isomorphic to the example of Kondō.
