Fix a valuation v of F and let p be the residue characteristic at v . For any prime number e9d75c30832f6a1218fe3d6cd2" title="Click to view the MathML source">ℓ≠p, the representation ρℓ gives rise to a representation e9fa17ff61"> of the Weil–Deligne group. In the case where A has semistable reduction at v it was shown in a previous paper that, with some restrictions, these representations form a compatible system of Q-rational representations with values in bf6c9b7689c7c290234c6ccdb5848" title="Click to view the MathML source">GA.
