Deformations of pseudocharacters and Mazur's finiteness condition
Abstract
We show that deformation rings of -pseudocharacters of a profinite group are noetherian, when satisfies Mazur's finiteness condition. The proof proceeds by reduction to the case when is finitely generated, where the result was previously established by the second author. This enables us to extend our work on moduli spaces of -condensed representations of a finitely generated profinite group , to the groups satisfying Mazur's finiteness condition. We also show that the functor from rigid analytic spaces over to sets, which associates to a rigid space the set of continuous -valued -pseudocharacters of is representable by a quasi-Stein rigid analytic space, and we study its general properties. We expect these results to be useful, when studying global Galois representations.
