摘要

在给定伽罗瓦群和最小可能分支素数的情况下，我们证明了对有理函数域的伽罗瓦扩展进行计数的大有限域版的Boston-Markin猜想。我们的证明涉及到机架(直接产品)结构群的研究。

The tamely ramified geometric quantitative minimal ramification problem

We prove a large finite field version of the Boston–Markin conjecture on counting Galois extensions of the rational function field with a given Galois group and the smallest possible number of ramified primes. Our proof involves a study of structure groups of (direct products of) racks.
