Abstract
Let be a cuspidal, cohomological automorphic representation of an inner form of over a number field of arbitrary signature. Further, let be a prime of such that is split at and the local component of at is the Steinberg representation. Assuming that the representation is non-critical at we construct automorphic -invariants for the representation . If the number field is totally real, we show that these automorphic -invariants agree with the Fontaine-Mazur -invariant of the associated -adic Galois representation. This generalizes a recent result of Spiess respectively Rosso and the first named author from the case of parallel weight to arbitrary cohomological weights.
