Differentiability of models with corners and (extended) charts #
In this file, we analyse the differentiability of charts, models with corners and extended charts. We show that
- models with corners are differentiable
- charts are differentiable on their source
mdifferentiableOn_extChartAt:extChartAtis differentiable on its source
Suppose a partial homeomorphism e is differentiable. This file shows
PartialHomeomorph.MDifferentiable.mfderiv: its derivative is a continuous linear equivalencePartialHomeomorph.MDifferentiable.mfderiv_bijective: its derivative is bijective; there are also spelling with trivial kernel and full range
In particular, (extended) charts have bijective differential.
