正熵有理曲面的自同构

Automorphisms of rational surfaces with positive entropy

Julie Déserti, Julien Grivaux

摘要:

Cantat证明了具有正拓扑熵的自同构的复紧曲面是环面、K3曲面、Enriques曲面或有理曲面。有理曲面的自同构是一个非常神秘的概念,近年来已成为人们深入研究的对象。本文构造了具有正拓扑熵的有理曲面自同构的几个新例子。我们还解释了如何定义和计算参数的家庭的双有理映射的复杂的射影平面和家庭的理性表面。

英文摘要:

A complex compact surface which carries an automorphism of positive topological entropy has been proved by Cantat to be either a torus, a K3 surface, an Enriques surface or a rational surface. Automorphisms of rational surfaces are quite mysterious and have been recently the object of intensive studies. In this paper, we construct several new examples of automorphisms of rational surfaces with positive topological entropy. We also explain how to define and to count parameters in families of birational maps of the complex projective plane and in families of rational surfaces.
