Abstract
Let be a prime number, a finite unramified extension of and a finite extension of . For any reducible two-dimensional representation of over , we compute explicitly the associated \'etale -module defined by Breuil-Herzig-Hu-Morra-Schraen. Then we let be an admissible smooth representation of over occurring in some Hecke eigenspaces of the mod cohomology and be its underlying two-dimensional representation of over . Assuming that is maximally non-split, we prove under some genericity assumption that the associated \'etale -module defined by Breuil-Herzig-Hu-Morra-Schraen is isomorphic to . This extends the results of Breuil-Herzig-Hu-Morra-Schraen, where was assumed to be semisimple.
