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…

The moduli space of cyclic covers in positive characteristic

Huy Dang, Matthias Hippold

We study the $p$ -rank stratification of the moduli space $A S W_{(d_{1}, d_{2}, \dots, d_{n})}$ , which represents $Z / p^{n}$ -covers in characteristic $p > 0$ whose $\mathbb{Z}/…

The refined local lifting problem for cyclic covers of order four

Huy Dang

Suppose $ϕ$ is a $Z /4$ -cover of a curve over an algebraically closed field $k$ of characteristic $2$ , and $Φ_{1}$ is a \emph{nice} lift of $ϕ$ 's $Z /2$ -sub-cover to…

Deforming cyclic covers in towers

Huy Dang

Obus-Wewers and Pop recently resolved a long-standing conjecture by Oort that says: every cyclic cover of a curve in characteristic $p > 0$ lifts to characteristic zero. Saïdi furthe…

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…

Local Oort groups and the isolated differential data criterion

Huy Dang, Soumyadip Das, Kostas Karagiannis +2

It is conjectured that if k is an algebraically closed field of characteristic p > 0, then any branched G-cover of smooth projective k-curves where the "KGB" obstruction vanishes a…

Connectedness of The Moduli Space of Artin-Schreier Curves of Fixed Genus

Huy Dang

We study the moduli space $A S_{g}$ of Artin-Schreier curves of genus $g$ over an algebraically closed field $k$ of positive characteristic $p$ . The moduli space is partit…
