The contributions presented in this volume address graduatestudents as wellas researchers. They are intelligible andpedagogically well-written reviewsof the most recentdevelopments in quantum field theory and both quantumgravity and quantum supergravity. Alongside technicalproblems of field quantization the reader will also findcareful discussions of the conceptual framework and ofapplications to quantum cosmology.
