K3曲面自同构中的第三小Salem数

The third smallest Salem number in automorphisms of K3 surfaces

Keiji Oguiso

摘要:

我们将已知第三小Salem数的对数同时实现为具有Siegel圆盘和点态不动曲线的K3曲面自同构的拓扑熵。我们还表明,对数的Lehmer数,已知的最小的Salem数,是不能实现的任何Enriques表面自同构的拓扑熵。这些结果完全是受McMullen的工作和Mathematica程序的启发。

英文摘要:

We realize the logarithm of the third smallest known Salem number as the topological entropy of a K3 surface automorphism with a Siegel disk and a pointwisely fixed curve at the same time. We also show the logarithm of the Lehmer number, the smallest known Salem number, is not realizable as the topological entropy of any Enriques surface automorphism. These results are entirely inspired by McMullen's works and Mathematica programs.
