# The Work of Robert Langlands

## Introduction

Robert P. Langlands was born in New Westminster, British Columbia, in 1936. He graduated from the University of British Columbia with an undergraduate degree in 1957 and an M.Sc. in 1958, and from Yale University with a Ph.D. in 1960. He has held faculty positions at Princeton University and Yale University, and is currently a Professor at the Institute for Advanced Study in Princeton New Jersey. He has won several awards recognizing his outstanding contributions to the theory of automorphic forms.

With the intention that the works be published eventually, perhaps posthumously if there is still an audience, Robert Langlands's papers and some of his correspondence and lectures are being collected on this site in a uniform format. This site has absorbed an earlier site created by Bill Casselman and most of the comments not directly attributed to Langlands himself are from Casselman's pen. The collection of papers is essentially complete; letters will be added as they turn up. The young Langlands made no systematic effort to retain copies of his correspondence.

This material is being put into $\TeX$ at the Institute for Advanced Study in Princeton New Jersey and will appear here as it becomes ready. We would like to thank Alice Garber, Dorothea Phares, Marietta Chiorello, Elly Gustafsson, Michelle Huguenin, and Carol Warfield of the present and former staff at the Institute, as well as Mark Goresky, for helping with this project. Above all we thank Bill Casselman for the initial suggestion, for a good deal of the original work, and for continuing advice. At present Anthony Pulido is responsible for the site. Questions and comments should be addressed to him.

## The Material

Inevitably, the topics into which we have organized material overlap somewhat.
