 Orateur(s) Eugen HELLMANN - University of Texas, Titre Density of potentially Barsotti-Tate representations Date 01/07/2013 Horaire 09:30 à 10:30 Diffusion Résume Let $K$ be a finite extension of $Q_p$. We prove that the Galois representations that become Barsotti-Tate after an abelian extension are Zariski-dense in the generic fiber of the universal deformation ring of an absolutely irreducible 2-dimensional residual Galois representation. The proof uses a map from an eigenvariety to the space of trianguline representations and a related density statement on the eigenvariety as a global input. This is joint work with Benjamin Schraen.
