Le halo spectral
[The spectral halo]
Annales scientifiques de l'École Normale Supérieure, Série 4, Tome 51 (2018) no. 3, pp. 603-655.

We construct a space of overconvergent modular forms of characteristic p, a compact operator on this space and we show that the characteristic series of this operator is the reduction modulo p of Coleman's universal series. We prove that finite slope overconvergent modular forms in positive characteristic can be deformed to characteristic 0.

Nous construisons un espace de formes surconvergentes en caractéristique p, un opérateur compact sur cet espace et nous montrons que la série caractéristique de cet opérateur est la réduction modulo p de la série universelle de Coleman. Nous démontrons que les formes surconvergentes en caractéristique p de pente finie se déforment vers la caractéristique 0.
