A bstract The proper definition of subsystems in gauge theory and gravity requires an
extension of the local phase space by including edge mode fields. Their role is on the one …

A bstract In this paper we provide a Chern-Simons gravity dual of a two dimensional
conformal field theory on a manifold with boundaries, so called boundary conformal field …

We provide an account of the issue of Gibbons-Hawking-York-like boundary terms for a
gravity theory defined on a Riemann-Cartan spacetime. We further discuss different criteria …

We consider 3-dimensional Euclidean gravity in the weak coupling limit of Smolin and show
that it is BF-theory with $\text {U (1)}^ 3$ as a Lie group. The theory is quantised using loop …

We determine the complex geometries dual to the semi-classical saddles in three-
dimensional gravity with positive or negative cosmological constant. We examine the semi …

We show that the solution corresponding to the gravitational field of a point particle at rest in
2+ 1 nonprojectable Hořava is exactly the same as 2+ 1 general relativity with the same …

We consider the issue of attaining a consistent Hamiltonian formulation, after a 3+ 1 splitting,
of a well-defined action principle for asymptotically flat gravity. More precisely, our starting …

We provide an account of the issue of Gibbons-Hawking-York-like boundary terms for a
gravity theory defined on a Riemman-Cartan spacetime. We further discuss different criteria …

We compute the vacuum energy of three-dimensional asymptotically flat space based on a
Chern–Simons formulation for the Poincaré group. The equivalent action is nothing but the …

Given a theory in a region of space-time with boundaries, defined by a Lagrangian, we
propose a method to find the corresponding theory at the boundary (either space-like or time …
