A note on invariable generation of nonsolvable permutation groups

Joachim König, Gicheol Shin

We prove a result on the asymptotic proportion of randomly chosen pairs of permutations in the symmetric group which "invariably" generate a nonsolvable subgroup, i.e., whose…

On unramified solvable extensions of small number fields

Joachim König

We investigate unramified extensions of number fields with prescribed solvable Galois group and certain extra conditions. In particular, we are interested in the minimal degree of…

Density results for specialization sets of Galois covers

Joachim König, François Legrand

We provide evidence for this conclusion: given a finite Galois cover of group , almost all (in a density sense) realizations of ov…

Rational pullbacks of Galois covers

Pierre Dèbes, Joachim König, François Legrand +1

The finite subgroups of are shown to be the only finite groups with this property: for some integer (depending on ), all Galois covers $X\rig…

An approach for computing families of multi-branch-point covers and applications for symplectic Galois groups

Dominik Barth, Joachim König, Andreas Wenz

We propose an approach for the computation of multi-parameter families of Galois extensions with prescribed ramification type. More precisely, we combine existing deformation and i…

Some examples of quadratic fields with finite nonsolvable maximal unramified extensions II

Kwang-Seob Kim, Joachim König

Let be a number field and be the maximal extension of that is unramified at all places. In a previous article, the first author found three real quadratic fields $…
