A vielbein formulation of unified Einstein-Maxwell theory

Abstract:
In the framework of J -bundles a vielbein formulation of unified Einstein– Maxwell theory is proposed. In the resulting scheme, field equations matching the gravitational and electromagnetic fields are derived by constraining a 5- dimensional variational principle. No dynamical scalar field in involved.
