Zariski density of crystalline points
arXiv:2206.06944 · doi:10.1073/pnas.2221042120
Abstract
We show that crystalline points are Zariski dense in the deformation space of a representation of the absolute Galois group of a -adic field. We also show that these points are dense in the subspace parameterizing deformations with determinant equal to a fixed crystalline character. Our proof is purely local and works for all -adic fields and all residual Galois representations.
