## What are the prerequisites for 'Introduction to Smooth Manifolds” by Lee?

. There are many people who have contributed to the development of this book in indispensable ways. Over any smooth coordinate domain U C M, the coordinate frame 8f8x i is a smooth local frame, so by Proposition 5. Problem 3-8 shows that the set of equivalence classes is in one-to-one correspondence with TpM. Similarly, show that a X is the point where the line through s Problems 29 and x intersects the same subspace. Remember, it is only when F is a diffeomorphism that F.

Our definition of the tangent space leads to a very natural interpretation of tangent vectors to smooth curves in manifolds. Conversely, if F is smooth, show that its restriction to any open subset is smooth. If U is an open set containing A. Admittedly, these terms do not make a lot of sense, but by now they are well entrenched, and we will see them again in Chapter 1 1. The Appendix which most readers should read, or at least skim, first contains a cursory summary of the prerequisite material on topology, lin­ ear algebra, and calculus that is used throughout the book. It focuses on developing an in- mate acquaintance with the geometric meaning of curvature.

As set in the case of vector fields, {p E M : u p tf 0}. Show that the assumption that A is closed is necessary in the ex­ tension lemma Lemma 2. The chapter begins with the definition of vector bundles and descriptions of a few examples. However, we will continue 98 4. This time I plan to thank them by not writing a book for a while. Its image set is c. Show that U is locally finite if and only if each set in U intersects only finitely many other sets in U.

## Introduction to Smooth Manifolds

Suppose M is a smooth manifold and f : M -+ 1Rk is a smooth function. Recall from Chapter 1 that every finite-dimensional vector space has a natural smooth manifold structure that is independent of any choice of basis or norm. If M and M are connected smooth manifolds, a smooth covering map 1r : M -+ M is a smooth surjective map with the property that every p E M has a connected neighborhood U such that each component of 1r - 1 U is mapped diffeomorphically onto U by 1r. There are also some typographical improvements in this edition. Next we explore how pushforwards look in coordinates. Regular Points and Singular Points. We will describe one significant application of Lie brackets later in this chapter, and we will see others in Chapters 12, 18, 19, and 20.

Here the main tools are the inverse function theorem and its corollaries. An invertible Lie algebra homomorphism is called a Lie algebra isomorphism. Many of the important properties of smooth covering maps follow from the existence of smooth local sections. It takes a bit more work to construct a local trivialization whose domain includes the fiber where the gluing took place. I try to keep the approach as concrete as possible, with pictures and intuitive discussions of how one should think geometrically about the abstract concepts, but without shying away from the powerful tools that modern mathematics has to offer.

It is a smooth map be­ cause its coordinate representation with respect to any of the graph coordinates of Example 1. Its goal is to familiarize students with the tools they will need in order to use manifolds in mathematical or scientific research--- smooth structures, tangent vectors and covectors, vector bundles, immersed and embedded submanifolds, tensors, differential forms, de Rham cohomology, vector fields, flows, foliations, Lie derivatives, Lie groups, Lie algebras, and more. It turns out that the answer to the question depends in a subtle way on the shape of the domain, as the next example illustrates. At any rate, there are many excellent textbooks on topology, such as the one by Lee himself, as well as Dugundji, Munkres, Stillwell recommended! We will always explicitly write summation signs in such expressions. Parts of every chapter have been substantially rewritten to improve clarity.

Moreover, for each fixed p E U n V, the map v. Let V and W be smooth vector fields on a smooth manifold M. The Riemannian Volume Form Hypersurfaces in Riemannian Manifolds Problems. For example, I introduce Riemannian metrics, but I do not go into connections or curvature. The next result is an analogue of Proposition 3. An angle function on a p subset U c § 1 is a continuous function } : U --t R such that e iB p for all p E U.

Because the line integrals 144 6. The Cotangent Bundle Po Figure 6. The value of wp X for any other vector X is then obtained by linear interpolation or extrapolation. They will be used throughout the book for building global smooth objects out of ones that are initially defined only locally.
