Differential Forms,old theory, through two applications. First, as we will see in Chapter 14, they are the objects that can be integrated in a coordinate-independent way over manifolds or submanifolds; second, as we will see in Chapter 15, they provide a link between analysis and topology by way of de Rham cohomology.

Vector Bundles, this kind of structure arises quite frequently—a collection of vector spaces, one for each point in ., glued together in a way that looks . like the Cartesian product of . with ℝ., but globally may be “twisted.” Such a structure is called a vector bundle.

Tensors,ns in a coordinate-independent way. In this chapter we carry this idea much further, by generalizing from linear objects to multilinear ones. This leads to the concepts of tensors and tensor fields on manifolds.

Orientations, by the vectors. These signs will cause problems, however, when we try to integrate differential forms on manifolds, for the simple reason that the transformation law for an .-form under a change of coordinates involves the determinant of the Jacobian, while the change of variables formula for multiple integrals involves the . of the determinant.

De Rham Cohomology, of the manifold, connected with the existence of “holes” of higher dimensions. Making this dependence quantitative leads to a new set of invariants of smooth manifolds, called the de Rham cohomology groups, which are the subject of this chapter.
