Galois representations for even general special orthogonal groups

  title={Galois representations for even general special orthogonal groups},
  author={Arno Kret and Sug Woo Shin},
  journal={arXiv: Number Theory},
We prove the existence of $\mathrm{GSpin}_{2n}$-valued Galois representations corresponding to cohomological cuspidal automorphic representations of certain quasi-split forms of $\mathrm{GSO}_{2n}$ under the local hypotheses that there is a Steinberg component and that the archimedean parameters are regular for the standard representation. This is based on the cohomology of Shimura varieties of abelian type, of type $D^{\mathbb{H}}$, arising from forms of $\mathrm{GSO}_{2n}$. As an application… Expand

Motivic Galois representations valued in Spin groups
Let $m$ be an integer such that $m \geq 7$ and $m \equiv 0,1,7 \mod 8$. We construct strictly compatible systems of representations of $\Gamma_{\mathbb Q} \to \mathrm{Spin}_m(\overline{\mathbb Q}_l)Expand
Points on Shimura varieties modulo primes
We survey recent developments on the Langlands–Rapoport conjecture for Shimura varieties modulo primes and an analogous conjecture for Igusa varieties. We discuss resulting implications on theExpand


Deformations of Galois representations and exceptional monodromy
For any simple algebraic group G of exceptional type, we construct geometric $$\ell $$ℓ-adic Galois representations with algebraic monodromy group equal to G, in particular producing the first suchExpand
Automorphy and irreducibility of some l-adic representations
Abstract In this paper we prove that a pure, regular, totally odd, polarizable weakly compatible system of $l$-adic representations is potentially automorphic. The innovation is that we make noExpand
The sign of Galois representations attached to automorphic forms for unitary groups
Abstract Let K be a CM number field and GK its absolute Galois group. A representation of GK is said to be polarized if it is isomorphic to the contragredient of its outer complex conjugate, up to aExpand

Automorphy for some l-adic lifts of automorphic mod l Galois representations
We extend the methods of Wiles and of Taylor and Wiles from GL2 to higher rank unitary groups and establish the automorphy of suitable conjugate self-dual, regular (de Rham with distinct Hodge–TateExpand
