Torsion formulation of gravity
We make it precise what it means to have a connection with torsion as solution of the Einstein equations. While locally the theory remains the same, the new formulation allows for topologies that would have been excluded in the standard formulation of gravity. In this formulation it is possible to couple arbitrary torsion to gauge fields without breaking the gauge invariance.
متن کاملIsominkowskian Formulation of Gravity
We submit the viewpoint that, perhaps, some of the controversies in gravitation occurred during this century are not due to insufficiencies of Einstein’s field equations, but rather to insufficiencies in the mathematics used for their treatment. For this purpose we treat the same equations with the novel, broader isomathematics and related isominkowskian geometry, and show an apparently final r...
متن کاملEuclidean 2D Gravity with Torsion
Closing a gap in the literature on the subject, the local solutions of 2D-gravity with torsion are given for Euclidean signature. For the topology of a cylinder the system is quantized in a Dirac approach.
متن کاملConformal dynamics of quantum gravity with torsion
The trace anomaly induced dynamics of the conformal factor is investigated in four-dimensional quantum gravity with torsion. The constraints for the coupling constants of torsion matter interaction are obtained in the infrared stable fixed point of the effective scalar theory. ⋆ On leave from Pedagogical Institute, 634041 Tomsk, Russia In a recent paper [1] the trace anomaly induced dynamics of...
متن کاملNonlinear electrodynamics in 3D gravity with torsion
We study exact solutions of nonlinear electrodynamics coupled to 3D gravity with torsion. We show that in any static and spherically symmetric configuration, at least one component of the electromagnetic field has to vanish. In the electric sector of the theory, we construct an exact solution, characterized by the azimuthal electric field. When the electromagnetic action is modified by a topolo...
