General Relativity from conservation laws without the principle of least action
Idan Talshir
We prove that the field equations of general relativity and other metric theories can be derived from the conservation of energy-momentum without using the assumption of least acti…
Massles multi gravity: Covariant, stable, two-derivative interacting massless multi-graviton theories
Idan Talshir
We present a general model of interacting metric fields with the sum of massless non-interacting spin 2 fields as the linear limit. In the non-interacting limit the model is reduce…
Stable Bimetric Theories
Idan Talshir
We prove that there are energetically stable bimetric theories. These theories satisfies a positive energy theorem. We construct a model example.
First order formalism for bimetric theories with connection interaction
Idan Talshir
We construct a first order Lagrangian formalism for bimetric theories with an interaction which is a general function of metrics and their derivatives, including non-analytic funct…
Energy and momentum in multiple metric theories
Idan Talshir
We derive the expressions for canonical energy, momentum, and angular momentum for multiple metric theories. We prove that although the metric fields are generally interacting, the…
