This book covers some recent advances in string theory and extra dimensions. Intended mainly for advanced graduate students in theoretical physics, it presents

The relation between quantum theory and the theory of gravitation remains one of the most outstanding unresolved issues of modern physics. According to general

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional poin

Recent developments in supersymmetric field theory, string theory, and brane theory have been revolutionary. The main focus of the present volume is development
