| Aug 3, 2022 at 7:36 | comment | added | Kim | Is there a basic example where the study of a Galois representation at a ramified place is used to deduce interesting consequences? | |

| Aug 2, 2022 at 9:24 | comment | added | Kim | Aside from lifts of the Frobenius in the local Galois group, are there even any other non-trivial elements of the global absolute Galois group that we can describe? | |

| Aug 2, 2022 at 8:35 | comment | added | Kim | Thanks! I don't know exactly what I'm looking for but this is a very helpful answer. Can a general representation coming from etale cohomology can be realized as a sequence of finite Galois representations? | |
