Book Description
The proceedings of the First Iberian Meeting on Gravity give a broad view of the most recent research on gravity. Black hole thermodynamics, wormhole solutions and covariant path integral quantization are some of the topics discussed. The mainstream approaches to quantum gravity, such as loop space quantization and string theories, are presented. Also included are the trendy subjects of two-dimensional quantum gravity and unitary matrix models.

Book Description
Classical and quantum gravity covers all aspects of gravitational physics and the theory of spacetime. This new book presents topical research in the study of classical and quantum gravity, including the weak field limit of fourth order gravity; the problem of time in quantum gravity; quantum correction and entropy spectrum in different gravity; quantum instability for charged particles on charged Nariai Black Holes and the equivalence of the generalised tetra formalism with the theory of general relativity.

Book Description
This thesis explores the connection between gravity and thermodynamics and provides a unification scheme that opens up new directions of exploration. Further elaborating on the Hawking effect and the possibility of singularity avoidance, the author not only discusses the information loss paradox at a broader level but also provides a possible solution to it. As the final frontier, it describes some novel effects arising from the microscopic structure of spacetime. Taken as a whole, the thesis addresses three major research areas in gravitational physics: it starts with classical gravity, proceeds to the black hole information loss paradox, and closes with Planck scale physics. The thesis is written in a lucid and pedagogical style, with an introduction accessible to researchers from other branches of physics and a d iscussion presenting open questions and future directions, which will benefit and hopefully inspire next-generation researchers.

Book Description
It is often claimed that Einstein's magnum opus—-his 1915 theory of General Relativity—-is distinguished from other theories of space and time in virtue of its background independence. It's also often claimed that background independence is an essential feature of any quantum theory of gravity. But are these claims true? This book aspires to offer definitive answers to both of these questions, by (a) charting the space of possible definitions of background independence, and (b) applying said definitions to various classical and quantum theories of gravity. The outcome, in brief, is as follows: General Relativity is not unique by virtue of its background independence (and, indeed, fails to be background independent on some popular definitions); moreover, the situation in the case of quantum theories of gravity is delicate, because (i) there are viable such theories which (by some accounts, at least) fail to be background independent, but also (ii) theories (e.g. perturbative string theory) which have often been dismissed for (allegedly) being background dependent in fact, on many accounts, are better classified as background independent. In giving these answers in rigorous detail, this book seeks to elevate the standards and generality of future discussions of background independence in the foundations of spacetime theories.
