To be or not to be local

Christophe Breuil, Florian Herzig, Yongquan Hu +4

Let $p$ be a prime number and $K$ a finite unramified extension of $Q_{p}$ . For a smooth representation $π$ of $GL_{2} (K)$ occurring in some Hecke eigenspace of the m…

On the constituents of the mod $p$ cohomology of Shimura curves

Christophe Breuil, Florian Herzig, Yongquan Hu +2

Let $p$ be a prime number and $K$ a finite unramified extension of $Q_{p}$ . When $p$ is large enough with respect to $[K : Q_{p}]$ and under mild genericity assumptions…

Finite length for unramified $GL_{2}$

Christophe Breuil, Florian Herzig, Yongquan Hu +2

Let $p$ be a prime number and $K$ a finite unramified extension of $Q_{p}$ . If $p$ is large enough with respect to $[K : Q_{p}]$ and under mild genericity assumptions,…

Generic decompositions of Deligne--Lusztig representations

Daniel Le, Bao V. Le Hung, Brandon Levin +1

Let $G_{0}$ be a reductive group over $F_{p}$ with simply connected derived subgroup, (geometrically) connected center and Coxeter number $h + 1$ . We extend Jantzen's generic de…
