In classical differential geometry, given a real, smooth maifold M , the differential df of a real smooth function f lives in the cotangential bundle of M . Differential forms and orthonormal frames don't appear until nearly the end of the book. The two-forms agree on the intersection of two open sets in the cover and hence define a global two-form. A homework from one of the most wonderful classes I've ever taken, Differential Geometry, taught by a brilliant and lovely man, Dr. Olivier Brahic, On the infinitesimal Gauge Symmetries of closed forms (arXiv). Let 𝔤 be some Lie 2-algebra. This issue; for example, diffeological, differential, and Frölicher structures are defined on arbitrary sets. This has given me the chance to apply differential-geometric techniques to problems which I used to believe could only be approached analytically. When the underlying principal 2-bundle over a smooth manifold X is topologically trivial, then the connections on it are identified with Lie 2-algebra valued differential forms on X . Examples of 2-connections with vanishing 2-form curvature obtained from geometric quantization are discusssed in. Euclidean geometry was abandoned in favour of di erential geometry and classical eld theories had to be quantized. I came across a beautiful pedagogical approach to E&M recently, which is clearly explained in the article Teaching Electromagnetic Field Theory Using Differential Forms by Warnick, Selfridge, and Arnold. This definitely is a text for physicists, not mathematicians, with the geometry taking a back-seat. I see: Maybe I should be more careful when I talk about “differential forms”. The book treats differential forms and uses them to study some local and global aspects of the differential geometry of surfaces. We are going to call this a "differential 1-form", but we would do well to notice the things that our text is not telling us - first that this construction implies we are working over a 3-manifold (Euclidean flat, sure enough), and moreover that is a vector in the co-tangent space to this manifold. Recall from the discussion there what such form data looks like. The naive view of a tangent will have it "sticking out" into some surrounding (one says embedding) space, and this we cannot allow - we want to do intrinsic geometry.
