,Stokes’ Theorem,If . is a manifold and . a submanifold, then any differential form on . induces a form on .. We can view this as a very special case of the inverse image of a form, under the embedding (injection) map.

Differential Calculus,my book on real analysis [La 93] give a self-contained and complete treatment for Banach spaces. We summarize certain facts concerning their properties as topological vector spaces, and then we summarize differential calculus. . and start immediately with Chapter II if the reader is accustomed to th

Vector Bundles,al glueing procedure can be used to construct more general objects known as vector bundles, which give powerful invariants of a given manifold. (For an interesting theorem see Mazur [Maz 61].) In this chapter, we develop purely formally certain functorial constructions having to do with vector bundl

Operations on Vector Fields and Differential Forms,g forms.” Applying it to the tangent bundle, we call the sections of our new bundle differential forms. One can define formally certain relations between functions, vector fields, and differential forms which lie at the foundations of differential and Riemannian geometry. We shall give the basic sys

Covariant Derivatives and Geodesics,ssumed to be C. unless otherwise specified. We let X be a manifold. We denote the .-vector space of vector fields by ΓT(X). Observe that ΓT(X) is also a module over the ring of functions.We let π:TX →Xbe the natural map of the tangent bundle onto X.

Volume Forms,ose extension to the infinite dimensional case is not evident. So this chapter is devoted to these forms of maximal degree. In the next chapter, we shall study how to integrate them, so the present chapter also provides a transition from the differential theory to the integration theory.

,Applications of Stokes’ Theorem,the computation of the maximal de Rham cohomology (the space of all forms of maximal degree modulo the subspace of exact forms); some come from Riemannian geometry; and some come from complex manifolds, as in Cauchy’s theorem and the Poincaré residue theorem. I hope that the selection of topics will
