Level lowering: a Mazur principle in higher dimension

Pascal Boyer

For a maximal ideal $m$ of some anemic Hecke algebra $T_{ξ}^{S}$ of a similitude group of signature $(1, d - 1)$ , one can associate a Galois $F_{l}$ -re…

Torsion classes in the cohomology of KHT Shimura varieties

Pascal Boyer

A particular case of Bergeron-Venkatesh's conjecture predicts that torsion classes in the cohomology of Shimura varieties are rather rare. According to this and for Kottwitz-Harris…
