The Breuil—Mézard conjecture relates the special fibers of local Galois deformation rings to the mod p reduction of types for GL(n). The known cases of this relation have powerful global consequences, and provide evidence for the existence of a p-adic local Langlands correspondence.

In this talk we show that the conjecture implies an analogous statement for discrete series Galois deformations and unit groups of p-adic central division algebras. The main step is to construct a Jacquet—Langlands transfer of Serre weights to GL(n), and to prove its compatibility with the reduction of types: this requires to prove a conjecture of Broussous, Sécherre and Stevens on the explicit description of the Jacquet—Langlands correspondence.
