Bonjour,
La plupart des titres et libellés est automatiquement traduite par `babel` (l'option `french` est à mettre avec les options de classe. classe). Pour les autres (il y en a 5, me semble-t-il, semble-t-il) il suffit d'utiliser la commande `\providecaptionname` qui figure 10 fois dans le fichier de classe (5 pour l'anglais, 5e pour l'allemand).
Je me suis permis de remplacer le chargement de `palatino`, qui est obsolète et ne gère pas les mathématiques, par le chargement de `newpx`, qui est basé sur `TeX Gyre Pagella`, un clone de palatino qui les gère, et dispose de vraies petites capitales. Enfin,il me semble qu'il vaut mieux charger `biblatex` avec pour moteur `biber`, bien plus puissant que `bibtex`.
Je n'ai pas traduit `\authorship`, parce qu'il me semble qu'on ne demande pas en France de certifier que c'est bien vous l'auteur de la thèse. Voici donc un préambule possible.
