The symposium held in honour of the 60th birthday of Graeme Segal brought together leading physicists and mathematicians. Its topics were centred around string

This is a monograph on geometrical and topological features which arise in quantum field theory. It is well known that when a chiral fermion interacts with a ga

This volume, based on lectures and short communications at a summer school in Villa de Leyva, Colombia (July 2005), offers an introduction to some recent develo

The remarkable developments in differential topology and how these recent advances have been applied as a primary research tool in quantum field theory are pres

The first title in a new series, this book explores topics from classical and quantum mechanics and field theory. The material is presented at a level between t
