Diffeomorphisms

This file implements diffeomorphisms.

Definitions

• Diffeomorph I I' M M' n: n-times continuously differentiable diffeomorphism between M and M' with respect to I and I'; we do not introduce a separate definition for the case n = ∞; we use notation instead.
• Diffeomorph.toHomeomorph: reinterpret a diffeomorphism as a homeomorphism.
• ContinuousLinearEquiv.toDiffeomorph: reinterpret a continuous equivalence as a diffeomorphism.
• ModelWithCorners.transDiffeomorph: compose a given ModelWithCorners with a diffeomorphism between the old and the new target spaces. Useful, e.g, to turn any finite dimensional manifold into a manifold modelled on a Euclidean space.
• Diffeomorph.toTransDiffeomorph: the identity diffeomorphism between M with model I and M with model I.trans_diffeomorph e.

Notations

• M ≃ₘ^n⟮I, I'⟯ M' := Diffeomorph I J M N n
• M ≃ₘ⟮I, I'⟯ M' := Diffeomorph I J M N ⊤
• E ≃ₘ^n[𝕜] E' := E ≃ₘ^n⟮𝓘(𝕜, E), 𝓘(𝕜, E')⟯ E'
• E ≃ₘ[𝕜] E' := E ≃ₘ⟮𝓘(𝕜, E), 𝓘(𝕜, E')⟯ E'

Implementation notes

This notion of diffeomorphism is needed although there is already a notion of structomorphism because structomorphisms do not allow the model spaces H and H' of the two manifolds to be different, i.e. for a structomorphism one has to impose H = H' which is often not the case in practice.
