Minimal ramification and the inverse Galois problem over the rational function field $\mathbb{F}_p(t)$

Abstract

The inverse Galois problem is concerned with finding a Galois extension of a field KK with given Galois group. In this paper we consider the particular case where the base field is K=\Fp(t)K=\F_p(t). We give a conjectural formula for the minimal number of primes, both finite and infinite, ramified in GG-extensions of KK, and give theoretical and computational proofs for many cases of this conjecture.
