某些单临界多项式迭代的伽罗瓦群

Galois groups of iterates of some unicritical polynomials

Michael R. Bush, Wade Hindes, Nicole R. Looper

摘要:

证明了某些单临界多项式的树实伽罗瓦表示在循环群的无限圈积圈积中具有有限指数,并证明了一些小次数例子的满射性,包括一个新的二次多项式族.要做到这一点,我们使用当地的技术,包括Chabauty-Coleman方法和Mordell-Weil筛的组合。

英文摘要:

We prove that the arboreal Galois representations attached to certain unicritical polynomials have finite index in an infinite wreath product of cyclic groups, and we prove surjectivity for some small degree examples, including a new family of quadratic polynomials. To do this, we use a combination of local techniques including the Chabauty-Coleman method and the Mordell-Weil sieve.
