For example, classically scale invariant field theories, where scale invariance is broken by quantum effects, provide an explanation of the flatness of inflationary potentials, as long as the theory can be studied through perturbation… The Haag–Kastler axiomatic framework for quantum field theory, introduced by Haag and Kastler (1964), is an application to local quantum physics of C*-algebra theory. The main difference is that these quantum gravity studies assume the quantum laws to be set as fundamental laws. In such a framework, the fractal geometry of space-time at the Planck scale is a consequence of the quantum nature of physical… As the study of the statistical mechanics of black-body radiation led to the advent of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the understanding of… Since the supersymmetry (SUSY) generators form together with the Poincaré algebra a superalgebra, called the super-Poincaré algebra, supersymmetry a gauge theory makes gravity arise in a natural way. The equations governing ordinary gravity in free space can be obtained from an action, by applying the variational principle to a certain action.
The problem of finding the quantum theory of the gravitational field, and thus understanding what is quantum spacetime, is still open. One of the most active of the current approaches is loop quantum.

Following chapters move on to consider knot theories, braid theories and extended loop representations in quantum gravity. A final chapter assesses the current status of the theory and points out possible directions for future research. Reviews of the Loops, Knots, Gauge Theories and Quantum Gravity Academia.edu is a platform for academics to share research papers. Relativity [7–9]. We will present and use the covariant approach to Loop Quantum Gravity. The covariant approach to Loop Quantum Gravity, or, spinfoam quantization pro-gram, is interlinked, inspired and based on the results of its parent theory, Loop Quan-tum Gravity. The Hamiltonian will in this sense be implicit. How is loop quantum gravity related to the principle of relativity, in particular to the diffeomorphism invariance of general relativity? the thing to focus on is a relatively recent formulation of Lqg called "covariant Lqg". If I google that, I get: and also the Cambridge UP page for the book International Loop Quantum Gravity Seminar. This is a seminar on research that takes place every Tuesday at 9am (US Central Time).

It is a theory that has grown historically via a long indirect path, briefly summarized at the end of this chapter. The book does not follows the historical path. Rather, it is pedagogical, taking the reader through the steps needed to learn the theory.
