# Books written by Edward Witten.

In 1990, Witten became the first physicist to be awarded a Fields Medal by the International Mathematical Union, awarded for his 1981 proof of the positive energy theorem in general relativity. Michael Atiyah commented for the ICM of Witten "Time and again he has surprised the mathematical community by a brilliant application of physical insight leading to new and deep mathematical theorems."

## Lectures on Geometry

This volume contains a collection of papers based on lectures delivered by distinguished mathematicians at Clay Mathematics Institute events over the past few years. It is intended to be the first in an occasional series of volumes of CMI lectures. Although not explicitly linked, the topics in this inaugural volume have a common flavour and a common appeal to all who are interested in recent developments in geometry.

## Superstring Theory, Volume 1: Introduction

This two-volume book attempts to meet the need for a systematic exposition of superstring theory and its applications accessible to as wide an audience as possible.

## Superstring Theory, Volume 2: Loop Amplitudes, Anomalies and Phenomenology

This two-volume book attempts to meet the need for a systematic exposition of superstring theory and its applications accessible to as wide an audience as possible.

## Quantum Fields and Strings: A Course for Mathematicians, Vol. 1

In 1996-97 the Institute for Advanced Study organized a special year-long program designed to teach mathematicians the basic physical ideas which underlie the mathematical applications. These volumes are a written record of the program.
