IsNonarchimedeanLocalField
Given a topological field K equipped with an equivalence class of valuations (a ValuativeRel),
we say that it is a non-archimedean local field if the topology comes from the given valuation,
and it is locally compact and non-discrete.
This implies the following typeclasses via inferInstance
- IsValuativeTopology K
- LocallyCompactSpace K
- IsTopologicalDivisionRing K
- ValuativeRel.IsNontrivial K
- ValuativeRel.IsRankLeOne K
- ValuativeRel.IsDiscrete K
- IsDiscreteValuationRing 𝒪[K]
- Finite 𝓀[K]
Assuming we have a compatible UniformSpace K instance
(e.g. via IsTopologicalAddGroup.toUniformSpace and isUniformAddGroup_of_addCommGroup) then
- CompleteSpace K
- CompleteSpace 𝒪[K]
