On rational connectedness and parametrization of finite Galois extensions

Daniel Krashen, Danny Neftin

Given two -Galois extensions of , is there an extension of that specializes to both? The equivalence relation on -Galois extension of , i…

The Grunwald problem and homogeneous spaces with non-solvable stabilisers

Elyes Boughattas, Danny Neftin

We give an affirmative answer to the Grunwald problem for new families of non-solvable finite groups G, away from the set of primes dividing |G|. Furthermore, we show that such G v…

Polynomial compositions with large monodromy groups and applications to arithmetic dynamics

Joachim König, Danny Neftin, Shai Rosenberg

For a composition of polynomials of degrees with alternating or symmetric monodromy group, we show that the monodromy…

Sylow-conjugate number fields

Alexander Lubotzky, Danny Neftin

By a classical result of Neukirch and Uchida, a number field K is determined by the structure of its absolute Galois group Gal(K). We show that K is not determined by the structure…

The Hilbert-Grunwald specialization property over number fields

Joachim König, Danny Neftin

Given a finite group and a number field , we investigate the following question: Does there exist a Galois extension with group whose set of specializations yie…

On parametric and generic polynomials with one parameter

Pierre Dèbes, Joachim König, François Legrand +1

Given fields , our results concern one parameter -parametric polynomials over , and their relation to generic polynomials. The former are polynomials $P(T,Y) \…
