HERMANN WEYL LE CTUR ES

The Hermann Weyl Lectures are organized and sponsored by the School of Mathematics of the Institute for Advanced Study.

Their aim is

to provide broad surveys of various topics in mathematics, accessible to nonspecialists, to be published eventually in the Annals of Mathematics Studies. The present monograph is the third in the series.

It is an outgrowth

of the sixth set of Hermann Weyl Lectures, which consisted of six lectures given by Professor J. F. Adams at the Institute for Advanced Study on March 18, 19, 24, 26, April 1, 2, 1975.

PREFACE

This book derives from a series of Hermann Weyl Lectures which I gave at the Institute for Advanced Study, Princeton, in the spring of 1975. It is a pleasure to thank my hosts for their invitation, their hospitality, and for providing so discriminating an audience. for my delay in submitting this manuscript.

I should also apologize

In the intervening time some

progress has been made with the theory, and I have taken the opportunity to mention some of it below.

Moreover, a number of other sources have

appeared, and of these [96] and [99] can be recommended as particularly useful to experienced topologists who want to see the results of the sub­ ject.

However, my object has been a more elementary exposition, which I

hope may convey the basic ideas of the subject in a way as nearly pain­ less as I can make it.

In this the Princeton audience encouraged me; the

more I found means to omit the technical details, the more they seemed to like it.

If that is the reaction of seasoned topologists, I hope that begin­

ners may find it useful to have a gentle introduction to the ideas used in the current literature. I am very grateful to J. P. May, B. J. Sanderson and S. B. Priddy for reading the first draft of this book, in part or in whole; I have benefited greatly from their comments. It goes without saying that I accept the re­ sponsibility for any jokes which remain.
