Apr 20, 2018 at 20:23 | comment | added | Ryan Budney | My DG lecture notes develop Ehresmann's framework somewhat. They're really only partially inspired by his work. The formalism is fairly minimalist. There are no groupoids, no categories, there are no abstract manifolds -- everything is with submanifolds of $\mathbb R^n$. So it's probably not what you want, but here they are: rybu.org/sites/default/files/math_docs/dgnotes/… One of the more interesting aspects of this formalism is how little work it takes to compute things like the Riemann curvature tensor for typical examples. | |
