Constraining images of quadratic arboreal representations

Andrea Ferraguti, Carlo Pagano

In this paper, we prove several results on finitely generated dynamical Galois groups attached to quadratic polynomials. First we show that, over global fields, quadratic post-crit…

Exceptional scatteredness in prime degree

Andrea Ferraguti, Giacomo Micheli

Let $q$ be an odd prime power and $n$ be a positive integer. Let $ℓ \in F_{q^{n}} [x]$ be a $q$ -linearised $t$ -scattered polynomial of linearized degree $r$ . Let $d=\max\{t,…
