|
Let k be a perfect field of characteristic p>0. A. Petrov
has recently constructed a projective, smooth scheme X/W(k), of
relative dimension p+1, such that the Hodge to de Rham spectral
sequence of X_0/k, where X_0 = X \otimes_{W(k}k, does not degenerate
at E_1, thus solving a question of Deligne-Illusie left open since
1987. I will explain the main ideas of the proof, which uses inputs from
Bhatt-Lurie's theory of diffracted Hodge complexes and combines
techniques of homotopical algebra and representation theory of algebraic
groups.

Une introduction à la conjecture d'André-Oort |

Jussieu |
| La conjecture d'André-Oort donne une description précise de de la distribution des points spéciaux (ou CM) sur les
variétés de Shimura. Elle a été prouvée - en admettant GRH - par Klingler, Ullmo, Yafaev puis inconditionnellement,
par une méthode très différente, d'abord pour les variétés de Shimura abéliennes, par Pila et Tsimerman et enfin récemment en toute
généralité par Pila, Shankar et Tsimerman, en s'appuyant sur un travail de Binyamini, Schmidt et Yafaev.
Je présenterai un survol des mathématiques impliquées, en m'appuyant sur les analogies avec des preuves de la conjecture de Manin-Mumford. |
