Timelike surfaces in Lorentz covariant loop gravity and spin foam models
Sergei Alexandrov, Zoltan Kadar
We construct a canonical formulation of general relativity for the case of a timelike foliation of spacetime. The formulation possesses explicit covariance with respect to Lorentz…

Polygon model from first order gravity
Z. Kadar
The gauge fixed polygon model of 2+1 gravity with zero cosmological constant and arbitrary number of spinless point particles is reconstructed from the first order formalism of the…

(2+1) gravity for higher genus in the polygon model
Z. Kadar, R. Loll
We construct explicitly a (12g-12)-dimensional space P of unconstrained and independent initial data for 't Hooft's polygon model of (2+1) gravity for vacuum spacetimes with compac…
