Theoretical problems in nonsymmetric gravitational theory.
Rapid Communications are intended for important new results which deserve accelerated publication, and are therefore given priority in editorial processing and production AR.apid Communication in Physical Review D should be no longer than jk~e printed pages and must be accompanied by an abstract Page .proofs are sent to authors, but because of the accelerated schedule, publication is generally ...
متن کاملNonsymmetric Gravitational Theory
A new version of nonsymmetric gravitational theory is presented. The field equations are expanded about the Minkowski metric, giving in lowest order the linear Einstein field equations and massive Proca field equations for the antisymmetric field g [µν]. An expansion about an arbitrary Einstein background metric yields massive Proca field equations with couplings to only physical modes. It foll...
متن کاملGravitational Waves in the Nonsymmetric Gravitational Theory
We prove that the flux of gravitational radiation from an isolated source in the Nonsymmetric Gravitational Theory is identical to that found in Einstein’s General Theory of Relativity.
متن کاملNonsymmetric Gravitational Theory as a String Theory
It is shown that the new version of nonsymmetric gravitational theory (NGT) corresponds in the linear approximation to linear Einstein gravity theory and antisymmetric tensor potential field equations with a non-conserved string source current. The Hamiltonian for the antisymmetric field equations is bounded from below and describes the exchange of a spin 1+ massive vector boson between open st...
متن کاملDynamical Constraints in the Nonsymmetric Gravitational Theory
We impose in the nonsymmetric gravitational theory, by means of Lagrange multiplier fields in the action, a set of covariant constraints on the antisymmetric tensor field. The canonical Hamiltonian constraints in the weak field approximation for the antisymmetric sector yield a Hamiltonian energy bounded from below. An analysis of the Cauchy evolution, in terms of an expansion of the antisymmet...
