Properties of the volume operator in loop quantum gravity: I. Results
We analyze the spectral properties of the volume operator of Ashtekar and Lewandowski in loop quantum gravity, which is the quantum analog of the classical volume expression for regions in
Quantum theory of geometry: I. Area operators
A new functional calculus, developed recently for a fully non-perturbative treatment of quantum gravity, is used to begin a systematic construction of a quantum theory of geometry. Regulated
Are the spectra of geometrical operators in Loop Quantum Gravity really discrete
One of the celebrated results of Loop Quantum Gravity (LQG) is the discreteness of the spectrum of geometrical operators such as length, area and volume operators. This is an indication that Planck

The state space of Loop Quantum Gravity admits a decomposition into orthogonal subspaces associated to diffeomorphism equivalence classes of graphs. In this paper I discuss the possibility of
Properties of the volume operator in loop quantum gravity: II. Detailed presentation
The properties of the volume operator in loop quantum gravity, as constructed by Ashtekar and Lewandowski, are analyzed for the first time at generic vertices of valence greater than four. We find
Linking topological quantum field theory and nonperturbative quantum gravity
Quantum gravity is studied nonperturbatively in the case in which space has a boundary with finite area. A natural set of boundary conditions is studied in the Euclidean signature theory in which the
Simplification of the spectral analysis of the volume operator in loop quantum gravity
The volume operator plays a crucial role in the definition of the quantum dynamics of loop quantum gravity (LQG). Efficient calculations for dynamical problems of LQG can therefore be performed only
A new realization of quantum geometry
We construct in this article a new realization of quantum geometry, which is obtained by quantizing the recently-introduced flux formulation of loop quantum gravity. In this framework, the vacuum is
Loop Quantum Gravity and the Meaning of Diffeomorphism Invariance
This series of lectures gives an introduction to the non-perturbative and background-independent formulation for a quantum theory of gravitation which is called loop quantum gravity. The Hilbert

TLDR
These results make possible the construction of a correspondence between any three-geometry whose curvature is small in Planck units and a diffeomorphism-invariant state of the gravitational and matter fields.
Extended loop representation of quantum gravity.
TLDR
A new representation of quantum gravity is developed based on an extension of the group of loops that behaves locally as an infinite dimensional Lie group and it is shown that the constraints are linear in the momenta.

A quantum Hamiltonian which evolves the gravitational field according to time as measured by constant surfaces of a scalar field is defined through a regularization procedure based on the loop

TLDR
It is shown that there exist quantum states which approximate a given metric at large scales, but such states exhibit a discrete structure at the Planck scale.

TLDR
The quantum fermions plus gravity system (QGD) is studied using the loop representation and the fermion dynamics is the immediate extension of pure gravity dynamics to open loops.
