View on Github →chore(Mathlib/LinearAlgebra/Basis): Move results about vector spaces to a new file (#6321)
This breaks a dependency cycle with Module.Free
, which means we can immediately show that all vector spaces are free modules.
The lemmas are moved without modification in this PR. A subsequent PR can use the Module.Free
results to golf the vector space ones, and deduplicate the API.
