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.

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.
