NSF 2.0: A spin weight zero formulation of General Relativity
Melina Bordcoch, Carlos Kozameh, Alejandra Rojas
We present a set of three PDEs for three real scalars that are equivalent to the full Einstein equations without any symmetry assumptions. The main variables in this formulation ar…
Null Surfaces and the Bach Equations
Mirta Iriondo, Carlos N. Kozameh, Alejandra Rojas
It is shown that the integrability conditions that arise in the Null Surface Formulation (NSF) of general relativity (GR) impose a field equation on the local null surfaces which i…
Null Surfaces and Legendre Submanifolds
Mirta Iriondo, Carlos Kozameh, Alejandra Rojas
It is shown that the main variable Z of the Null Surface Formulation of GR is the generating function of a constrained Lagrange submanifold that lives on the energy surface H=0 and…
