On lifting representations and actions on curves of the metacyclic groups $C_{p^{s}} ⋊ C_{m}$

Huy Dang, Adrian Vasiu

For a prime $p$ , a pair $(s, m) \in N^{2}$ with $m$ relatively prime to $p$ , a homomorphism $χ : C_{m} \to Aut (C_{p^{s}})$ , and an algebraically closed field $k$ …

$a$ -Numbers of Cyclic Degree $p^{2}$ Covers of the Projective Line

Huy Dang, Steven R. Groen

We investigate the $a$ -numbers of $Z / p^{2} Z$ -covers in characteristic $p > 2$ and extend a technique originally introduced by Farnell and Pries for $\mathbb{Z}/p\math…

Hurwitz trees and deformations of Artin-Schreier covers

Huy Dang

Let $R$ be a complete discrete valuation ring of equal characteristic $p > 0$ . Given a $Z / p$ -Galois cover of a formal disc over $R$ , one can derive from it a semi-stable mod…
