The local dimension of a finite group over a number field

Joachim König, Danny Neftin

Let $G$ be a finite group and $K$ a number field. We construct a $G$ -extension $E / F$ , with $F$ of transcendence degree $2$ over $K$ , that specializes to all $G$ -extensions of $K_\m…

Symmetric Galois Groups Under Specialization

Tali Monderer, Danny Neftin

Given an irreducible bivariate polynomial $f (t, x) \in Q [t, x]$ , what groups $H$ appear as the Galois group of $f (t_{0}, x)$ for infinitely many $t_{0} \in Q$ ? How often d…

Reducible Fibers of Polynomial Maps

Joachim König, Danny Neftin

For a degree $n$ polynomial $f$ over the rationals, the elements in the fiber $f^{- 1} (a)$ are of degree $n$ over $Q$ for most rational values $a$ by Hilbert's irreducibilit…
