A Connectedness Criterion for `-adic Galois Representations
نویسندگان
چکیده
To every compatible system of Galois representations of a global field K, there is associated a natural invariant K conn , the smallest extension of K over which the associated algebraic monodromy groups become connected. We present a purely field-theoretic construction of K conn for all Galois representations arising from cohomology.

On three-dimensional Galois representations
We give an irreducibility criterion for the Galois images of compatible l-adic systems of Galois representations. We apply this to the l-adic realizations of the van Geemen-Top motive M and prove an analogue of Serre’s theorem for M.
متن کاملOn the Eigencurve at Classical Weight One Points
We show that the p-adic Eigencurve is smooth at classical weight one points which are regular at p and give a precise criterion for etaleness over the weight space at those points. Our approach uses deformations of Galois representations.
متن کامل`-adic representations from Hurwitz spaces
The Hurwitz space approach to the regular Inverse Galois Problem was the only successful approach to Galois group realizations beyond nilpotent groups. It gave regular realizations of many series of groups. More significantly, the M(odular) T(ower) program identified obstructions to systematically finding regular realizations. Finding a way around those obstructions generalize renown results on...
متن کاملGALOIS MODULES AND p-ADIC REPRESENTATIONS
In this paper we develop a theory of class invariants associated to p-adic representations of absolute Galois groups of number fields. Our main tool for doing this involves a new way of describing certain Selmer groups attached to p-adic representations in terms of resolvends associated to torsors of finite group schemes.
متن کاملBanach-Hecke Algebras and p-Adic Galois Representations
In this paper, we take some initial steps towards illuminating the (hypothetical) p-adic local Langlands functoriality principle relating Galois representations of a p-adic field L and admissible unitary Banach space representations of G(L) when G is a split reductive group over L. 2000 Mathematics Subject Classification: 11F80, 11S37, 22E50
