View on Github →feat(geometry/manifold/diffeomorph): some additions needed for smooth vector bundles (#14738)
- Define
diffeomorph.prod_comm
,diffeomorph.prod_congr
,diffeomorph.prod_assoc
- Prove
cont_mdiff_on.comp_cont_mdiff
- In
fiber_bundle
, define some lemmas forlocal_triv_at
that were already there forlocal_triv
- Yes, this PR does a couple different things, but it is still very small
- This is part of #14412
