On a class of consistent linear higher spin equations on curved manifolds
Jörg Frauendiener, George A. J. Sparling
We analyze a class of linear wave equations for odd half spin that have a well posed initial value problem. We demonstrate consistency of the equations in curved space-times. They…
A definition of the Ponzano-Regge quantum gravity model in terms of surfaces
Junichi Iwasaki
We show that the partition function of the Ponzano-Regge quantum gravity model can be written as a sum over surfaces in a dimensional space-time. We suggest a geometrical m…
Spin Networks and Quantum Gravity
Carlo Rovelli, Lee Smolin
We introduce a new basis on the state space of non-perturbative quantum gravity. The states of this basis are linearly independent, are well defined in both the loop representation…
OUTLINE OF A GENERALLY COVARIANT QUANTUM FIELD THEORY AND A QUANTUM THEORY OF GRAVITY
Carlo Rovelli
We study a tentative generally covariant quantum field theory, denoted the T-Theory, as a tool to investigate the consistency of quantum general relativity. The theory describes th…
GR via Characteristic Surfaces
Simonetta Frittelli, Carlos Kozameh, Ted Newman
We reformulate the Einstein equations as equations for families of surfaces on a four-manifold. These surfaces eventually become characteristic surfaces for an Einstein metric (wit…
Lorentzian Metrics from Characteristic Surfaces
Simonetta Frittelli, Carlos Kozameh, Ted Newman
The following issue is raised and discussed; when do families of foliations by hypersurfaces on a given four dimensional manifold become the null surfaces of some unknown, but to b…
