Introduction

The aim of this book is to give an introduction to two-dimensional boundary conformal field theory (CFT) and an overview of its various applications to D-branes in string theory.

The study of two-dimensional scale invariant quantum field theories (QFTs) has a long history. Applications to important problems in various branches of physics are so numerous that CFT has established its position as one of the leading techniques in modern theoretical physics. Its first significant success was the exact computation of critical exponents for second-order phase transitions in two-dimensional statistical systems, such as the critical Ising model and many extensions thereof. Surface critical phenomena are still among the key applications, ...
