Foundations of Space and Time

Jeff Murugan is a Senior Lecturer in the Department of Mathematics and Applied Mathematics and a member of the Astrophysics, Cosmology and Gravity Centre, University of Cape Town. He is interested in all aspects of gravity and is currently working on string theory and connections between gauge theories and gravity. Amanda Weltman is a Lecturer in the Department of Mathematics and Applied Mathematics and a member of the Astrophysics, Cosmology and Gravity Centre, University of Cape Town. She works in the exciting bridging areas of string cosmology studying physical ways to test string theory within the context of cosmology. George F. R. Ellis is Emeritus Professor of Applied Mathematics and Honorary Research Associate in the Mathematics Department, University of Cape Town. He works on general relativity theory, cosmology, complex systems, and the way physics underlies the functioning of the human brain.

'Encapsulating the latest debates, this book details the different approaches to understanding the nature of space and time. It brings together leading researchers to explore in a comprehensive coverage all of the current approaches to solving the problems of quantum gravity, addressing the strengths and weaknesses of each approach, to give researchers and graduate students an up-to-date view of the world.'
