From the reviews: "Presents a selection of contributions presented at the workshop 'Mathematical and Physical aspects of Quantum Gravity' ... . presentation of various approaches to quantum gravity in one volume is rather unique and provides reader with an opportunity to compare their advantages and disadvantages. A significant advantage of this volume is that the articles are written in a less technical style, focusing only on major theoretical questions, with many contributions being accessible to non-specialists and thus providing a broad overview of this fascinating field of research."
