My entry in the Mathematical Genealogy Project.

Master‘s thesis: The Weil Representation and Its Character (Leiden, 2008)

This thesis is written in a rather arid style. The main goal is to review the construction of the metaplectic covering \( \widetilde{\text{Sp}}(2n) \twoheadrightarrow \text{Sp}(2n) \) and the Weil representation \( \omega_\psi \). After that, I described the Maslov cocycle and deduced the character formula for \( \omega_\psi \) of Maktouf-Thomas in terms of Maslov indices.

Doctoral Dissertation: Vers une formule des traces stable pour le groupe métaplectique (Jussieu, 2011)

The aim of my dissertation is twofold. First, a basic endoscopic framework for \( \widetilde{\text{Sp}}(2n) \) is laid down; in particular, the transfer and the fundamental lemma are established. Secondly, I tried to set up Arthur's invariant trace formula for a large class of covering groups of connected reductive groups \( \tilde{G} \twoheadrightarrow G(\mathbb{A}) \) over a number field, which is ultimately achieved in my later papers.
