Containing contributions from leading researchers in this field, this book provides a complete overview of this field from the frontiers of theoretical physics

The first comprehensive survey of (2+1)-dimensional quantum gravity - for graduate students and researchers.

This book addresses the subject of gravity theories in two and three spacetime dimensions. The prevailing philosophy is that lower dimensional models of gravity

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered su
