Quantum Geometry and Quantum Gravity
The purpose of this contribution is to give an introduction to quantum geometry and loop quantum gravity for a wide audience of both physicists and mathematicians. From a physical point of view the emphasis will be on conceptual issues concerning the relationship of the formalism with other more traditional approaches inspired in the treatment of the fundamental interactions in the standard mod...
متن کاملQuantum Gravity as a quantum field theory of simplicial geometry
This is an introduction to the group field theory approach to quantum gravity, with emphasis on motivations and basic formalism, more than on recent results; we elaborate on the various ingredients, both conceptual and formal, of the approach, giving some examples, and we discuss some perspectives of future developments.
متن کاملQuantum geometry of topological gravity
We study a c = −2 conformal field theory coupled to two-dimensional quantum gravity by means of dynamical triangulations. We define the geodesic distance r on the triangulated surface with N triangles, and show that dim[ rH ] = dim[N ], where the fractal dimension dH = 3.58 ± 0.04. This result lends support to the conjecture dH = −2α1/α−1, where α−n is the gravitational dressing exponent of a s...

Recently[1, 2, 3], it is shown that, the quantum effects of matter are well described by the conformal degree of freedom of the space–time metric. On the other hand, it is a wellknown fact that according to Einstein’s gravity theory, gravity and geometry are interconnected. In the new quantum gravity theory[1, 2, 3], matter quantum effects completely determine the conformal degree of freedom of...
متن کاملSpectral geometry and quantum gravity
Recent progress in quantum field theory and quantum gravity relies on mixed boundary conditions involving both normal and tangential derivatives of the quantized field. In particular, the occurrence of tangential derivatives in the boundary operator makes it possible to build a large number of new local invariants. The integration of linear combinations of such invariants of the orthogonal grou...
