具有整数乘子的二次有理映射

Quadratic rational maps with integer multipliers

Valentin Huguin

摘要:

本文证明了乘子都位于给定虚二次域的整数环内的二次有理映射是幂映射、Chebyshev映射或Lattès映射。特别是,这提供了一些证据,以支持一个猜想米尔诺有关理性地图的乘数都是整数。

英文摘要:

In this article, we prove that every quadratic rational map whose multipliers all lie in the ring of integers of a given imaginary quadratic field is a power map, a Chebyshev map or a Lattès map. In particular, this provides some evidence in support of a conjecture by Milnor concerning rational maps whose multipliers are all integers.
