This book provides the necessary foundation for students interested in any
of the diverse areas of mathematics which require the notion of a differentiable
manifold. It is designed as a beginning graduate-level textbook and presumes
a good undergraduate training in algebra and analysis plus some knowledge
It is
of point set topology, covering spaces, and the fundamental group.
also intended for use as a reference book since it includes a number of items
which are difficult to ferret out of the literature, in particular, the complete and
self-contained proofs of the fundamental theorems of Hodge and de Rham.
The core material is contained in Chapters I, 2, and 4. This includes
differentiable manifolds, tangent vectors, submanifolds, implicit function
theorems, vector fields, distributions and the Frobenius theorem, differential
forms, integration, Stokes' theorem, and de Rham cohomology.
Chapter 3 treats the foundations of Lie group theory, including the
relationship between Lie groups and their Lie algebras, the exponential
map, the adjoint representation, and the closed subgroup theorem. Many
examples are given, and many properties of the classical groups are derived.
The chapter concludes with a discussion of homogeneous manifolds. The
standard reference for Lie group theory for over two decades has been
Chevalley's Theory of Lie Groups, to which I am greatly indebted.
For the de Rham theorem, which is the main goal of Chapter 5, axiomatic
sheaf cohomology theory is developed. In addition to a proof of the strong
form of the de Rham theorem-the de Rham homomorphism given by
integration is a ring isomorphism from the de Rham cohomology ring to the
differentiable singular cohomology ring-it is proved that there are canonical
isomorphisms of all the classical cohomology theories on manifolds. The
pertinent parts of all these theories are developed in the text. The approach
which I have followed for axiomatic sheaf cohomology is due to H. Cartan,
who gave an exposition in his Seminaire 1950/1951.
For the Hodge theorem, a complete treatment of the local theory of
elliptic operators is presented in Chapter 6, using Fourier series as the basic
is presumed.
tool. Only a slight acquaintance with Hilbert spaces
I wish to thank Jerry Kazdan, who spent a large portion of the
summer of 1969 educating me to the whys and wherefores of inequalities
and who provided considerable assistance with the preparation of this chapter.
I also benefited from notes on lectures by J. J. Kohn and Stephen Andrea,
from several papers of Louis Nirenberg, and from Partial Differential

Equations by Bers, John, and Schechter, which the reader might wish to
consult for further references to the literature.
At the end of each chapter is a set of exercises. These are an integral
part of the text. Often where a claim in a chapter has been left to the reader,
there is a reminder in the Exercises that the reader should provide a proof
of the claim. Some exercises are routine and test general understanding
of the chapter. Many present significant extensions of the text. In some
cases the exercises contain major theorems. Two notable examples are
properties of the eigenfunctions of the Laplacian and the Peter-Weyl theorem,
which are developed in the Exercises for Chapter 6. Hints are provided for
many of the difficult exercises.
There are a few notable omissions in the text. I have not treated complex
manifolds, although the sheaf theory developed in Chapter 5 will provide
the reader with one of the basic tools for the study of complex manifolds.
Neither have I treated infinite dimensional manifolds, for which I refer the
reader to Lang's Introduction to Differentiable Manifolds, nor Sard's theorem
and imbedding theorems, which the reader can find in Sternberg's Lectures
on Differential Geometry.
Several possible courses can be based on this text. Typical one-semester
courses would cover the core material of Chapters 1, 2, and 4, and then
either Chapter 3 or 5 or 6, depending on the interests of the class. The
entire text can be covered in a one-year course.
Students who wish to continue with further study in differential geometry
should consult such advanced texts as Differential Geometry and Symmetric
Spaces by Helgason, Geometry of Manifolds by Bishop and Crittenden, and
Foundations of Differential Geometry (2 vols.) by Kobayashi and Nomizu.
I am happy to express my gratitude to Professor I. M. Singer, from whom
I learned much of the material in this book and whose courses have always
generated a great excitement and enthusiasm for the subject.
Many people generously devoted considerable time and effort to reading
early versions of the manuscript and making many corrections and helpful
suggestions. I particularly wish to thank Manfredo do Carmo, Jerry Kazdan,
Stuart Newberger, Marc Rieffel, John Thorpe, Nolan Wallach, Hung-Hsi Wu,
and the students in my classes at the University of California at Berkeley and
at the University of Pennsylvania. My special thanks to Jeanne Robinson,
Marian Griffiths, and Mary Ann Hipple for their excellent job of typing, and
to Nat Weintraub of Scott, Foresman and Company for his cooperation and
excellent guidance and assistance in the final preparation of the manuscript.

This Springer edition is a reproduction of the original Scott, Foresman
printing with the exception that the few mathematical and typographical
errors of which I am aware have been corrected. A few additional titles
have been added to the bibliography.
I am especially grateful to all those colleagues who wrote concerning
their experiences with the original edition. I received many fine suggestions
for improvements and extensions of the text and for some time debated the
possibility of writing an entirely new second edition. However, many of the
extensions I contemplated are easily accessible in a number of excellent
sources. Also, quite a few colleagues urged that I leave the text as it is.
Thus it is reprinted here basically unchanged. In particular, all of the
numbering and page references remain the same for the benefit of those
who have made specific references to this text in other publications.
In the past decade there have been remarkable advances in the applications
of analysis-especially the theory of elliptic partial differential equations, to
geometry-and in the application of geometry, especially the theory of
connections on principle fiber bundles, to physics. Some references to these
exciting developments as well as several excellent treatments of topics in
differential and Riemannian geometry, which students might wish to consult
in conjunction with or subsequent to this text, have been included in the
bibliography.
Finally, I want to thank Springer for encouraging me to republish this
text in the Graduate Texts in Mathematics series. I am delighted that it
has now come to pass.
