On the construction of some stacks of curves and surfaces [PDF]

open access: yes
In this thesis, we study some examples of moduli spaces in algebraic geometry, using the theory of stacks. More precisely, we study moduli stacks of curves and surfaces.

Explicit moduli spaces for curves of genus 1 and 2

open access: yes
In this thesis we study pairs of $N$-congruent elliptic curves. That is, we study pairs of elliptic curves whose $N$-torsion subgroups are isomorphic as Galois modules.

Abelian n-division fields of elliptic curves and Brauer groups of product Kummer and abelian surfaces

open access: yes, 2017
Let $Y$ be a principal homogeneous space of an abelian surface, or a K3 surface, over a finitely generated extension of $\mathbb{Q}$. In 2008, Skorobogatov and Zarhin showed that the Brauer group modulo algebraic classes $\mathrm{Br}{Y}/ \mathrm{Br}_1{Y}$

Étude arithmétique des paires dynamiques polynomiales

open access: yes, 2020
We study one-dimensional algebraic families of pairs given by a polynomial with a marked point. We prove an "unlikely intersection" statement for such pairs thereby exhibiting strong rigidity features for these pairs.

On the automorphism group of certain algebraic varieties [PDF]

open access: yes, 2012
We study the automorphism groups of two families of varieties. The first is the family of stable curves of low genus. To every such curve, we can associate a combinatorial object, a stable graph, which encode many properties of the curve.

The space of Cohen–Macaulay curves and related topics

open access: yes, 2014
The space of Cohen–Macaulay curves is a compactification of the space of curves that are embedded in a given projective space Pn. The idea is similar to that of the Hilbert scheme but instead of adding degenerated curves, one considers only curves ...
