Boundary Conformal Field Theory And The Worldsheet Approach To D Branes

A comprehensive introduction to the mathematical description of strings, D-branes and the geometry of strongly curved spacetime.

A concise introduction to string theory explaining central concepts, mathematical tools and recent developments in the field of physics. Covering fundamental concepts including how strings interact with each other, this book is perfect for students with no prior knowledge as well as scholars from other disciplines.

This 2017 volume, now reissued as OA, provides an accessible, detailed introduction to instanton methods and their many applications.

This volume summarizes the many modified theories of gravity and shows how to select physically viable models using symmetry principles.

This book offers a comprehensive discussion of developments at the interface of particle physics, supergravity, and cosmology, for graduates and researchers.

First published in 1973, this influential work discusses Einstein's General Theory of Relativity to show how two of its predictions arise: first, that the ultimate fate of many massive stars is to undergo gravitational collapse to form 'black holes'; and second, that there was a singularity in the past at the beginning of the universe. Starting with a precise formulation of the theory, including the necessary differential geometry, the authors discuss the significance of space-time curvature and examine the properties of a number of exact solutions of Einstein's field equations. They develop the theory of the causal structure of a general space-time, and use it to prove a number of theorems establishing the inevitability of singularities under certain conditions. A Foreword contributed by Abhay Ashtekar and a new Preface from George Ellis help put the volume into context of the developments in the field over the past fifty years.

A comprehensive account of new models of extra dimensions which form an important part of present-day high-energy physics.

This accessible volume provides a modern treatment of the cosmological and string-theoretic background necessary to understand inflation in string theory.
