Field Equations and Conservation Laws in the Nonsymmetric Gravitational Theory
نویسندگان
چکیده
The field equations in the nonsymmetric gravitational theory are derived from a Lagrangian density using a first-order formalism. Using the general covariance of the Lagrangian density, conservation laws and tensor identities are derived. Among these are the generalized Bianchi identities and the law of energy-momentum conservation. The Lagrangian density is expanded to second-order, and treated as an “Einstein plus fields” theory. From this, it is deduced that the energy is positive in the radiation zone. Typeset using REVTEX 1

Scalar Fields in The Nonsymmetric Kaluza–Klein (Jordan–Thiry) Theory**
In this paper we construct the Nonsymmetric Jordan–Thiry Theory unifying N.G.T., the Yang–Mills’ field, the Higgs’ fields and scalar forces in a geometric manner. In this way we get masses from higher dimensions. We discuss spontaneous symmetry breaking, the Higgs’ mechanism and a mass generation in the theory. The scalar field Ψ (as in the classical Jordan–Thiry Theory) is connected to the eff...
متن کاملLocal Cohomology in Field Theory
This is an introductory survey of the theory of p-form conservation laws in field theory. It is based upon a series of lectures given at the Second Mexican School on Gravitation and In these lectures I will provide a survey of some aspects of the theory of local coho-mology in field theory and provide some illustrative applications, primarily taken from the Einstein equations of the general the...
متن کاملCosmological Models in the Nonsymmetric Gravitational Theory
Cosmological consequences of the nonsymmetric gravitational theory (NGT) are studied. The structure of the NGT field equations is analyzed for an inhomogeneous and anisotropic universe, based on the spherically symmetric field equations. It is assumed that the matter density and pressure are purely time dependent, and it is shown that the field equations allow open, flat and closed universes. T...
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 کاملConservation laws of scaling-invariant field equations
A simple conservation law formula for field equations with a scaling symmetry is presented. The formula uses adjoint-symmetries of the given field equation and directly generates all local conservation laws for any conserved quantities having non-zero scaling weight. Applications to several soliton equations, fluid flow and nonlinear wave equations, Yang-Mills equations and the Einstein gravita...
