Construction of automorphic Galois representations. II. (English) Zbl 1310.11062
Let \(F\) be a totally real field and \(K\) a totally imaginary quadratic extension of \(F\). This paper constructs Galois representations associated to certain cuspidal automorphic representations of \(\mathrm{GL}(n,K)\): Let \(\Pi\) be a cuspidal automorphic representation of \(\mathrm{GL}(n,K)\) that is cohomological and ‘conjugate self-dual’. Then there exists a semi-simple continuous Galois representation \(\rho_{\iota,\Pi} : G_K \rightarrow \mathrm{GL}(n,\overline{\mathbb Q}_p)\) associated to \(\Pi\) (where \(\iota\) is are choices of embeddings of \(\overline{\mathbb Q}\) into \(\overline{\mathbb Q}_p\) and \(\mathbb C\)) which satisfying some local compatibility conditions at places \(v\) not dividing \(p\) and as well as dividing \(p\). This main result is achieved by constructing missing Galois representations for even degree \(F\) by \(p\)-adic approximation and has applications to automorphy lifting theorems.
