It is well known that, in the first-order formalism, pure three-dimensional gravity is just the BF theory. Similarly, four-dimensional general relativity can be formulated as BF theory with an additional constraint term added to the Lagrangian. In this paper we show that the same is true also for higher-dimensional Einstein gravity: in any dimension gravity can be described as a constrained BF theory. Moreover, in any dimension these constraints are quadratic in the B field. After describing in… 
New variables for classical and quantum gravity in all dimensions: I. Hamiltonian analysis
Loop quantum gravity (LQG) relies heavily on a connection formulation of general relativity such that (1) the connection Poisson commutes with itself and (2) the corresponding gauge group is compact.
Three-dimensional Quantum Supergravity and Supersymmetric Spin Foam Models
We show how super BF theory in any dimension can be quantized as a spin foam model, generalizing the situation for ordinary BF theory. This is a first step toward quantizing supergravity theories. We
Classical general relativity as BF-Plebanski theory with linear constraints
We investigate a formulation of continuum 4D gravity in terms of a constrained BF theory, in the spirit of the Plebanski formulation, but involving only linear constraints, of the type used recently
New variables for classical and quantum (super)-gravity in all dimensions
Supergravity was originally introduced in the hope of finding a theory of gravity without the shortcoming of perturbative non-renormalisability. Although this goal does not seem to have been reached
On the symmetries of BF models and their relation with gravity
The perturbative niteness of various topological models (e.g. BF models) has its origin in an extra symmetry of the gauge-xed action, the so-called vector su- persymmetry. Since an invariance of this
New variables for classical and quantum gravity in all dimensions: V. Isolated horizon boundary degrees of freedom
In this paper, we generalize the treatment of isolated horizons in loop quantum gravity, resulting in a Chern–Simons theory on the boundary in the four-dimensional case, to non-distorted isolated
An Action for higher spin gauge theory in four dimensions
An action principle is presented for Vasiliev's Bosonic higher spin gauge theory in four spacetime dimensions. The action is of the form of a broken topological field theory, and arises by an
On the implementation of the canonical quantum simplicity constraint
In this paper, we discuss several approaches to solve the quadratic and linear simplicity constraints in the context of the canonical formulations of higher dimensional general relativity and
General relativity from three-forms in seven dimensions
Topological quantum field theory and quantum gravity
This thesis is broadly split into two parts. In the first part, simple state sum models for minimally coupled fermion and scalar fields are constructed on a 1-manifold. The models are independent of
