I outlined a proof of the fact.
It’s about pages of not-so-easy complex analysis review. Some are routine explorations of the main material. Here is how he died: One then finds another neighborhood Z of f such that functions in the intersection of Y and Z are forced to be embeddings.

I’ve always viewed Ehresmann connections as the fundamental notion of connection.
If you want to learn Differential Topology study these in this order: You can do it by looking at coordinate patches, but the pseudo differential operators you define will depend on the coordinate chart you chose though usually the principal differentkal is invariant under coordinate change. I must teach myself all the stuff by reading books.
That’s certainly a nice list! If you are interested in learning Algebraic Geometry I recommend the books of my Amazon list. It asserts that the set of all singular values of any smooth manifold is a subset of measure zero. The proof consists of an inductive procedure and a diffefential version of an apprixmation result for maps between open subsets of Euclidean spaces, which is proved with the help of convolution kernels.

I would recommend Jost’s book “Riemannian geometry and geometric analysis” as well as Sharpe’s “Differential geometry”. Of course, I also agree that Guillemin and Pollack, Hirsch, and Milnor are great supplements, and will probably emphasize some of the topological aspects that Lee doesn’t go into.
I think it’s best suited for a second course in differential geometry after digesting a standard introductory treatment,like Petersen or DoCarmo.
They’re really best suited for a self-studying student working through them at his or her own pace. And of course, the same goes for his proofs. You can look at it on Google books to decide if it fits your style. In the years since its first publication, Guillemin and Pollack’s book has become a standard text on the subject.
In a slightly different direction, you can also look at Eli Stein’s “Topics in harmonic analysis related to the Littlewood Paley theory”. I personally found de Carmo to be a nice text, but I found Stoker to be far easier to read.
Clark 80k 9 A final mark above 5 is needed in order to pass the course. I have decided to fix this lacuna once for all. Differential geometry is a bit more difficult.
I used Tietze’s Extension Theorem and the fact that a smooth mapping to a sphere, which is defined on the boundary of a manifolds, extends smoothly to the whole manifold if and only if the degree is zero.
But then you are entering the world of abstract algebra. But I don’t know much in the way of great self-learning differential geometry texts, they’re all rather quirky special-interest textbooks or undergraduate-level grab-bags of light topics.
This is a very informative book which covers many important topics including nature and purpose of differential geometry, a concept of mapping, coordinates in Euclidean space, vectors in Euclidean space, basic rules of vector calculus in Euclidean space, tangent and normal plane, osculating plane, involutes, and evolutes, Bertrand curves etc. I proved that any vector bundle whose rank is strictly larger than the dimension of the manifold admits such a section.
Nevertheless, since its treatment is a bit dated, the kind of algebraic formulation is not used forget about pullbacks and functors, like Tu or Lee mentionthat is why an old fashion geometrical treatment may be very helpful to complement modern titles. About 50 of these books are 20th or 21st century books which would be useful as introductions to differential geometry.
Concerning embeddings, one first ueses the local result to find a neighborhood Y of a given embedding f in the strong topology, such that any map contained in this neighborhood is an embedding when restricted to the memebers of some open cover.
